Description:
This application claims priority from U.S. Provisional Patent Application Ser. No. 61/958,359, filed on Jul. 26, 2013, the entireties of which are expressly incorporated by reference herein. 
    
    
     FIELD OF THE INVENTION 
     The field of the invention generally relates to carrying bags and cases. More specifically, the invention relates to carrying bags that may have attachable, removable and exchangeable outer panels with printed graphics or pictures. 
     The field of the invention also generally relates to the manufacturing of attachable panels for carrying cases upon each sales order without the need to carry inventory of pre-printed attachable panels. 
     BACKGROUND OF THE INVENTION 
     There are many different types of carrying bags and cases on the market in the world. Some examples are 1) backpacks that may be used by students or others to carry books and other supplies, 2) business and computer bags used to carry laptops and other business supplies, 3) sports bags used to carry sporting goods, 4) musical instrument bags used to carry musical instruments and 5) travel bags and luggage to carry personal belongings. In addition to these examples, there are many other types of carrying bags on the market throughout the world. 
     In one example, musical instrument carrying bags and cases typically come in a variety of shapes and sizes depending on the types of musical instrument they are designed to hold. The bags and cases may also come in a variety of types, specifically, hard, soft, or hybrid type cases. Hard cases may comprise an outer shell that is hard and rigid, and may be made of harder materials such as plastic, metal such as aluminum, pressed leather or other harder materials. Soft cases, often referred to as gig bags, may comprise an outer shell that is softer and less ridged than a hard case, and may be made of softer materials such as polyester fabric, nylon fabric, canvas, softer leather or other materials. Often, these softer materials may be lined with a thin PVC or PU lining in order to add a small level of rigidity and durability to the shell. Hybrid cases are typically a combination of a hard case and a soft case, and may utilize a softer outside shell with a more rigid inner padding to increase the level of protection that the bag may provide to the musical instrument. 
     The cases and bags often also include a layer of foam padding on the interior of the case or bag on one or more sides to provide increased protection to the musical instrument that may be contained inside. The foam padding may protect the musical instrument inside the case if the case were to be dropped or were to receive a blow from a blunt object. The cases and bags often also include pockets on the front panel of the bag or case to carry musical sheets and binders, as well as other accessories such as picks, cords and straps. In addition, many musical instrument carrying bags and cases include side handles to carry the bag or case with one hand, and back pack straps on the back of the bag to secure the bag over the user&#39;s shoulders as a backpack would be secured and carried. 
     Many musical instrument bags and cases on the market currently are made of a single colored material, predominantly black. Others may use materials of other colors and a few may have colored graphics printed on the bags. However, these bags and cases are typically limited in variety and the colors and graphics are applied to the bags in a permanent fashion; that is, the colors and the graphics cannot be removed or changed. 
     It should be noted that creative people such as musicians may wish to express themselves and their own unique personalities by having graphics and artwork on their musical instrument bags and cases. However, there are no musical instrument bags that allow the user to apply a wide variety of graphics to the bags, or that allow the user themselves to apply their own colorful graphics or logos to the bags in a high quality manner. 
     In addition, the user may wish to express themselves with a particular graphic or logo on their bag one day, and then may wish to express themselves differently the next day with a different graphic or logo on their same bag. However, there are no musical instrument bags or cases that allow the user to change the graphics or logos on the bag or case as desired. In addition, having multiple bags that may have different graphics that may be used to express themselves differently may become costly due to the high cost of the bags. Also, musical cases and bags are often somewhat large, and having multiple bags may require a large amount of storage space to store the different bags when not in use. 
     The same may be said for other types of carrying bags such as backpacks, business and computer bags, sports bags, travel bags and other types of carrying bags. That is, the owners of these types of bags, as well as other types of bags not mentioned, may also be interested in expressing themselves with graphics and artwork on their carrying bags similar to musicians with their musical bags. And they too may wish to express themselves with one particular graphic design on their carrying bag on one day and a different graphical design on their carrying bag on another day. 
     From a manufacturing and business standpoint, it may be costly for a manufacturer of carrying bags to produce inventories of carrying bags with particular designs on them to sell to retail outlets and direct to customers. It may also be risky for a manufacturer of carrying bags to pick one or several designs to produce and to produce inventories of these particular designs in hopes that the carrying bags with these particular designs will be popular designs and will sell. If the designs are not popular, or fall out of popularity before the entire inventory is sold, the manufacturer may be stuck holding inventory of carrying bag designs that are no longer sellable and may be required to liquidate the inventory at a financial loss. 
     Accordingly, there is a need for an improved carrying bag or case of different types as described above that addresses the foregoing and other issues.

     In one embodiment as shown in  FIG. 1 , Velcro section  50  may include a strip of either Velcro loop fastener material or Velcro hook fastener material that may be sewn or attached by other means around the general circumference of front panel  20 . While this specification describes the hook and loop fastener material as Velcro brand, other manufactures of fastening material may also be used. In a preferred embodiment, Velcro strip  50  may be 0.5 inches wide, but other widths may also be used. 
     Velcro section  50  may be configured to receive and attach to Velcro section  120  that may be sewn or attached by other means around the general circumference of back side  110  of attachable panel  100  as shown in  FIG. 2 . As will be described in further detail in later sections, attachable panel  100  may have a front side  130  (not shown) and a back side  110  that may generally correspond in size and shape to front panel  20  of bag  10 . In addition, attachable panel  100  may comprise of a rugged material similar to the material used to manufacture the instrument bag such as polyester, nylon, canvas or other materials. Also, attachable panel  100  may include a liner material adhered to its back side  110  that may add stiffness to the attachable panel  100 . In a preferred embodiment, front side  130  of attachable panel  100  may contain graphics, pictures or other artwork that may be chosen or created by the user in order to express themselves through aesthetic means. 
     Attachable panel  100  may be secured to front panel  20  of gig bag  10  by placing attachable panel  100  onto front panel  20  such that Velcro section  50  and Velcro section  120  may generally align face-to-face, and by pressing Velcro section  120  onto Velcro section  50  such that they may mate and adhere to one another. It may be preferable that if Velcro section  50  may be a loop type of Velcro fastener, that Velcro section  120  may be a hook type of Velcro fastener such that the two Velcro sections may mate and adhere to one another when aligned and pressed together. It may also be preferable that if Velcro section  50  may be a hook type of Velcro fastener, that Velcro section  120  may be a loop type of Velcro fastener such that the two Velcro sections may mate and adhere to one another when aligned and pressed together. 
     As shown in the illustrated embodiment of  FIG. 1 , Velcro section  50  may be a generally continuous strip of Velcro fastening material that may extend around the general circumference of front panel  20  of guitar bag  10 . While  FIG. 1  shows Velcro section  50  as extending continuously around the general circumference of the front panel  20 , the Velcro section  50  may not be continuous and may be in sections. 
     In addition, Velcro section  50  may be sewn or otherwise attached to other locations on front panel  20  such as in the inner region instead of along the circumference. Also, Velcro strip  50  may be located in a variety of locations that may include the circumference, the inner regions and other regions of front panel  20 . 
     While  FIG. 1  depicts Velcro section  50  as generally being a strip, other shapes or patterns of Velcro may be used such as square patches, circular patches, and other shapes or patterns of Velcro that may be located in various locations on front panel  20 . 
     In addition, as shown in  FIG. 2 , Velcro section  120  may be a generally continuous strip of Velcro fastening material that may extend around the general circumference of back side  110  of attachable panel  100 . While  FIG. 2  shows Velcro section  120  as extending continuously around the general circumference of the back panel  110  of attachable panel  100 , the Velcro section  120  may not be continuous and may be in sections. 
     Also, Velcro section  120  may be sewn or otherwise attached to other locations on back side  110  of attachable panel  100  such as in the inner region instead of along the circumference. Also, Velcro strip  120  may be located in a variety of locations that may include the circumference, the inner regions and other regions of back side  110  of attachable panel  100 . 
     While  FIG. 2  depicts Velcro section  120  as generally being a strip, other shapes or patterns of Velcro may be used such as square patches, circular patches, and other shapes or patterns of Velcro that may be located in various locations on back side  110  of attachable panel  100 . 
     It may be preferable that at least some of the Velcro sections  120  on back side  110  of attachable panel  100  may align with at least some of the Velcro sections  50  on front panel  20  of bag  10  when attachable panel  100  is generally placed onto front panel  20  of bag  10  and the shape of attachable panel  100  is generally aligned with the shape of front panel  20  of bag  10 . In this generally aligned position, attachable panel  100  may be pressed onto front panel  20  of bag  10  such that such that at least some of the Velcro sections  50  on front panel  20  of bag  10  may mate and adhere to at least some of the Velcro sections  120  on the back side  110  of attachable panel  100 . In this configuration attachable panel  100  may be secured to the front face  20  of the instrument bag  10 . The resulting combination of the back side  110  of attachable panel  100  mated and secured to the front panel  20  of instrument carrying bag  10  as described above is shown in  FIG. 3 . 
     As shown in  FIG. 3 , the front side  130  of attachable panel  100  may be exposed and may generally cover the front panel  20  of instrument bag  10 . In this configuration, front side  130  of attachable panel  100  may contain graphical artwork, logos, printed pictures, or other types of images (not shown) that may be used to add aesthetic value to the instrument bag. 
     It should be noted that attachable panel  100  may be removed by pulling the attachable panel  100  away from front face  20  of gig bag  10  with adequate force to break the mating bond between Velcro sections  50  and  120 . In this way, one attachable panel  100  that may have specific graphical artwork printed on its front side  130  may be removed and replaced with another attachable panel  100  that may have different graphical artwork printed on its font side  130 . The procedure to do this may be for the user to pull an existing attachable panel  100  off the front panel  20  of bag  10  by gripping attachable panel  100  and pulling it away from the front panel  20  of bag  10  to release attachable panel  100  from bag  10 . The user may then generally align the shape of a new attachable panel  100  with the shape of front panel  20  of bag  10  and may press attachable panel  100  to front panel  20  of bag  10  to attach new attachable panel  100  to bag  10 . In this fashion, the user may remove and replace attachable panels  100  as they desire in order to change the graphical design shown on their carrying case at any time. The user may also purchase or otherwise acquire additional attachable panels  100  with brand new designs at any time to continually increase the selection of designs that they may attach to their carrying cases and bags. 
     It should also be noted that while  FIG. 3  shows the attachable panel  100  as generally resembling the size and shape of front panel  20  of instrument bag  10 , attachable panel  100  may not generally resemble the size and shape of front face  20  (not shown). In one example of this type, attachable panel  100  may cover only a portion of front face  20  and may therefore be any shape. In this embodiment it may be preferable that attachable panel  100  may fit generally within the entire or a portion of the outer contour of front face  20  but this may not be required. It may also be preferable that attachable panel  100  not extend past the outer circumference of front face  20  of bag  10 , but this may not be required. In addition, attachable panel  100  may be modified to fit within the contour of front panel  20  by folding, cutting or other modification techniques. 
     Graphical artwork may be printed on or otherwise affixed to the front side  130  of attachable panel  100  using a digital printing machine, a dye sublimation system, silk screening techniques, paint, decals, stickers or other means so that the customer may express themselves aesthetically through the artwork they choose for their bag. 
     While the descriptions thus far of the attachable panel  100  of  FIG. 2  and the instrument bag  10  of  FIG. 1  have mainly described the attachable panel  100  being removably attached to the front panel  20  of the instrument bag  10  by using Velcro fastening means, other means such as clips, pins, buttons, snaps, zippers, latches, grommets, magnets or other means may also be used. In these examples, the fastening means may be a part of the instrument bag  10  and the attachable panel  100  as described above with respect to using Velcro as the attachment means. Or, the attachment means may be a part of the instrument bag  10  only, the attachable panel  100  only, neither the bag  10  nor the attachable panel  100 , or any combination thereof. In addition, the fastening means may or may not remain as a part of the bag  10  or the attachable panel  100  when the attachable panel  100  may be removed. 
     For instance, in one embodiment, attachable panel  100  may be attached to the front panel  20  of bag  10  using a side zipper. That is, one side of the zipper may be attached around the general circumference of the attachable panel  100  and the other side of the zipper may be attached around the general circumference of the front panel  20  of the bag  10  such the two sides of the zipper may be zipped together to secure attachable panel  100  to the front panel  20  of bag  10 . In addition, the zipper may secure attachable panel  100  to bag  10  by being located in other areas on carrying bag  10  different than the circumference of bag  10 , located in other areas on attachable panel  100  different than the circumference of attachable panel  100 , or in any combination of circumference areas and non-circumference areas on bag  10  and attachable panel  100 . 
     In another embodiment, attachable panel  100  may be attached to the front panel  20  of bag  10  using snaps. That is, male sides of snaps may be positioned on the front panel  20  of the bag  10 , and female sides of snaps may be positioned in corresponding positions on attachable panel  100  such that when attachable panel  100  is generally aligned in position on front panel  20  of bag  10 , the male and female snap components may align and engage to affix panel  100  to front panel  20  of bag  10 . It may be preferable that if male sides of snaps are configured on the front panel  20  of bag  10  that female sides of snaps are configured in corresponding positions on attachable panel  100 , and that if female sides of snaps are configured on the front panel  20  of bag  10  that male sides of snaps are configured on the attachable panel  20 . 
     As described above, other attachment means may also be used to configure attachable panel  100  to front panel  20  of bag  10  such as latches and grommets, buttons pins, sewing methods, clips, rivets, magnets and other means. 
     In yet another embodiment, the attachable panel  100  may serve as the complete front panel  20  or as a part of the front panel  20  of the bag  10  such that all or a portion of the attachable panel  100  and all or a portion of the front panel  20  of the bag  10  may be one in the same. That is, a portion or the entirety of front panel  20  of bag  10  may comprise the attachable panel  100  and may be removed and replaced by another front panel  20  with different graphical artwork affixed to it. In this embodiment, the front panel  20  may be attached to the bag  10  with a zipper as described above, Velcro, snaps, clips or other means. 
     It should be noted that the invention described above may apply to all types of guitar cases and bags including hard cases, soft cases, gig bags, hybrid cases and bags, and other types of guitar bags and cases. Depending on the type of case, it may be preferable that different types of attachment means may be used to affix attachable panel  100  to front panel  20  of case  10 . For instance, for soft cases and hybrid cases, Velcro may be used as described above. However, for hard cases made of metal for example, magnets, snaps, latches or other means may be preferable. 
     It should also be noted that while the descriptions above describe the attachable panel as being attached to the front side  20  of the guitar gig bag  10 , the attachable panel  100  may also be attached to other sides or panels of the instrument bag  10  such as the side panel  30 , the back panel  40 , or to any other panels or sides, or to any combination of panels or sides of carrying case  10 , or to any other area on carrying case  10 . 
     Also, while the above descriptions describe a single attachable panel  208  being attached to a carrying case or bag  10 , multiple attachable panels may be attached to the carrying case or bag  10  individually or in unison using similar or different means as described above. Said multiple attachable panels may be attached to the front sides, side sides, back sides, or any other sides, regions, areas or combination of sides, regions and areas on the carrying case  10 . 
     In addition, while the description above primarily describes the attachment of attachable panel  100  to a guitar carrying bag or case  10 , the attachable panel  100  may be attached to other types of bags meant for carrying other types of instruments. Examples of this may include drum cases, drum stick cases, keyboard cases, horn cases, woodwind cases, violin cases and other types of musical instrument cases. 
     Also, the attachable panel  100  may be attached to other types of cases and bags that may be designed to carry other items or devices other than musical instruments. Such cases and bags may include laptop computer cases, personal backpacks, messenger bags, tablet computer cases, purses, phone cases, travel cases, sports bags and other types of cases and bags. 
     In one embodiment of a different type of carrying case or bag that may utilize an attachable panel, a backpack  200  as shown in  FIG. 6  may include a body  202 , a front side  204   a , a top opening  206 , a front pocket  220 , an attachable panel  208   a  and other components. Backpack may also include standard backpack-type straps (not shown) on the back of the bag  200  such that backpack  200  may be worn over the shoulders for hands-free carrying. 
     As shown in  FIG. 7 , backpack  200  may also include a top flap  210 . Top flap  210  may include a Velcro section  212  on its outer front side  228  as shown. As shown in  FIG. 8 , attachable panel  208   a  may include a Velcro section  218  on its back side  216 . In a preferred embodiment, Velcro section  212  on flap  210  of backpack  200  may be configured in position, size and shape to receive Velcro section  218  on the back side  216  of attachable panel  208   a . When Velcro sections  212  and  218  are mated accordingly, attachable panel  208   a  may be configured onto backpack  200  as shown in  FIG. 6 . It may be preferable that if Velcro section  212  is the hook side of Velcro, that Velcro section  218  may be the loop side of Velcro such that when Velcro section  212  and Velcro section  218  are pressed together that they may affix to each other. Conversely, it may be preferable that if Velcro section  212  is the loop side of Velcro, that Velcro section  218  may be the hook side of Velcro such that when Velcro section  212  and Velcro section  218  are pressed together that they may affix to each other. Pressing Velcro section  218  of attachable panel  208  of  FIG. 8  to mate with Velcro section  212  of  FIG. 7  may result in backpack  200  configured with attachable panel  208   a  as shown in  FIG. 6 . 
     It should be noted that flap  210  may be incorporated into the back side, front side, side sides or other sides of the backpack  200  and may not resemble a flap as shown in  FIG. 7 . Instead, flap  210  may be a portion of the back side, front side or other sides of the backpack. In this scenario, Velcro section  212  may be located on the back side, front side, side sides or other sides of the backpack  200 . 
     With Velcro section  212  mated and attached to Velcro section  218 , attachable panel  208   a  may be configured with backpack  200  and may generally extend from flap  210  over top opening  206  and down over the front  204   a  of backpack  200 . 
     In this configuration, attachable panel  208   a  may act as the top of backpack  200  and may cover top opening  206  of backpack  200 . Attachable panel  208   a  may also extend down the front  204   a  of backpack  200  and may or may not cover front pocket  220 . 
     In addition, the lower region of attachable panel  208   a  may be attached or otherwise secured to front side  204   a , or to other sides of backpack  200 , using Velcro, clips, snaps, buckles, straps with buckles, or other attachment means (not shown). With the lower region of attachable panel  208   a  affixed or otherwise secured to the front side  204   a  or other sides of backpack  200  in addition to the upper region of attachable panel  208  being affixed to flap  210  as described above, attachable panel  208   a  may act as a protective cover for backpack  200 , thus securing any contents within backpack  200  safely inside. Also, top opening  206  may include additional means to be securely held closed such as a zipper or multiple zippers, snaps, clasps, Velcro sections, a pull chord, latches or other securing means (not shown). 
     In another embodiment, attachable panel  208   b  may also include upper side flaps  222  that may extend outward on the left and right upper sides of attachable panel as shown in  FIG. 9 . As shown, Velcro section  218  may extend onto side flaps  222 . As described below, side flaps  222  may be used to provide additional strength to the bond between attachable panel  208   b  and upper flap  210  of backpack  200 . 
     To secure attachable panel  208   b  to flap  210  while utilizing side flaps  222 , attachable panel  208   b  may first be aligned with flap  210  as shown in  FIG. 10 . In this position, Velcro section  218  on back side  216  of attachable panel  208   b  may be facing downward while Velcro section  212  on upper flap  210  may be facing upward as shown. Attachable panel  208   b  may then be moved in the direction of arrows A in  FIG. 10  until it may overlap upper flap  210  as shown in  FIG. 11 . In this position, Velcro section  218  may be pressed onto Velcro section  212  such that the two Velcro sections may mate. It may be preferable that if Velcro section  212  may be loop Velcro then Velcro section  218  may be hook Velcro, and that if Velcro section  212  may be hook Velcro then Velcro section  218  may be loop Velcro. 
     In this embodiment, it may also be preferable that upper flap  210  may have additional back Velcro sections  224  on the general left and right regions on the back side  226  of upper flap  210  as shown in  FIG. 12 . 
     In the configuration as shown in  FIG. 11 , side flaps  222  may be folded over the edges of upper flap  210  until side flaps  222  may come into contact with the back side  226  of flap  210 . In this position, it may be preferable that the outer portions of Velcro section  218  on the left and right sides of side flaps  222  may come into contact and may mate with back Velcro sections  224  on the back side  226  of upper flap  210 . This is depicted in  FIG. 13  and  FIG. 14 .  FIG. 14  is a view looking in the direction of arrows B in  FIG. 13 . 
     It may be preferable that if Velcro section  218  is the hook side of Velcro, that Velcro sections  224  may be the loop side of Velcro such that when Velcro section  218  and Velcro sections  224  are pressed together that they may affix to each other. Conversely, it may be preferable that if Velcro section  218  is the loop side of Velcro, that Velcro sections  224  may be the hook side of Velcro such that when Velcro section  218  and Velcro sections  224  are pressed together that they may affix to each other. Pressing Velcro section  218  on the side flaps  222  of attachable panel  208   b  of  FIG. 8  to mate with Velcro sections  224  of  FIG. 7  may result in attachable panel  208   b  configured with flap  210  as shown in  FIG. 13 . 
     It should be stated that this configuration that may include side flaps  222  mated with the underside  226  of flap  210  via mated Velcro sections  218  and  224  may allow attachable panel  208   b  to be attached to upper flap  210  of backpack  200  with increased strength. That is, in this configuration, it may be more difficult for attachable panel  208   b  to be accidentally pulled off from upper flap  210 . Removing attachable panel  208   b  from this configuration may require that side flaps  222  may first need to be pulled away from the underneath back side  226  of flap  210  in order to disengage Velcro sections  224  on the back side  226  of flap  210  from the outer areas of Velcro section  218  on the back side  216  on the side flaps  222  of attachable panel  208   b , and then the attachable panel  208   b  may be pulled off the front side  228  of upper flap  210  in order to disengage Velcro section  218  on the back side  216  of attachable panel  208  from Velcro section  212  on the top side  228  of flap  210 . 
     In addition, attachable panel  208   c  when configured with upper flap  210  may not cover top opening  206  of backpack  200  as shown in  FIG. 15 . Instead, upper flap  210  may be configured in front of or otherwise to the side of top opening  206  as shown in  FIG. 16 . Attachable panel  208   c  may be configured and attached to flap  210  using the methods described above, but with flap  210  positioned in front of top opening  206  instead of behind top opening  206 , attachable panel  208   c  may not cover top opening  206  when configured with flap  210  of backpack  200  to extend from flap  210  down the front side  204   c  of backpack  200 . In this case, top opening  206  may include additional means to be securely held closed such as a zipper or multiple zippers, snaps, clasps, Velcro sections, a pull chord, latches or other securing means (not shown). 
     Also, backpack  200  may include multiple top openings  206  and attachable panel  208   c  may be configured to cover all multiple top openings  206 , several of multiple top openings  206 , one of multiple top openings  206  or no top openings  206 . As an example,  FIG. 17  depicts backpack with two top openings  206   a ,  206   b  separated by inner wall  222 . As shown, attachable panel  208   c  may be attached using attachment means as described above or by other means to the generally upper region of inner wall  222 , or to a flap (not shown) configured with the generally upper section of inner wall  222 , and may extend over front top opening  206   a  and down the front side  204   c  of backpack  200 . In this example, attachable panel  208   c  may not extend over top opening  206   a  since attachable panel  208   c  may be attached to the top of inner wall  222  which may be positioned in front of top opening  206   a . It may be understood however that if attachable panel  208   c  were attached behind top opening  206   a , that it may extend over both top opening  206   a  and top opening  206   b  and down the front side  204   c  of backpack  200  (not shown). In addition, it may be understood that if attachable panel  208   c  were attached in front of top opening  206   b , that it may extend down the front side  204   c  of backpack  200  but not extend over either top opening  206   a  or top opening  206   b . It will be obvious to someone skilled in the art that this example may be scaled to carrying bags that may include multiple top openings greater in number than two and that attachable panel  208   c  may be configured to cover all multiple top openings, several top openings, one top opening or no top openings, depending on where the upper region of attachable panel  208   c  may be attached to backpack  200 . 
     Another type of carrying bag that may be configured to include an attachable panel may be a type of bag often referred to as a messenger bag  300  as depicted in  FIG. 18 . As shown, messenger bag  300  may have similar characteristics and elements as backpack  200  described in earlier sections. Specifically, as shown in  FIG. 18 , messenger bag  300  may have a body  302 , a front side  304 , a top opening  306 , an attachable panel  308 , and other components. In addition, messenger bag  300  may also have a shoulder strap  316  to carry messenger bag  300  over the shoulders hands free. 
     It will be obvious to one skilled in the art that messenger bag  300  may resemble guitar bag  10  and backpack  200  with regards to the current invention such that the descriptions above for how the current invention may be incorporated with guitar bag  10  and backpack  200  may be directly applicable to how the current invention may be incorporated with messenger bag  300 . It will also be obvious to one skilled in the art that all of the variations and different configurations described in earlier sections of this specification in regards to guitar carrying case  10  and backpack  200  in relation to the current invention and how an attachable panel may be configured with guitar carrying bag  10  and backpack  200  may also apply to messenger bag  300  such that these variations and configurations need not be repeated here. 
     Yet another type of carrying bag that may be configured to include an attachable panel may be a duffle bag, often also referred to as a sports bag. As shown in  FIG. 19  duffle bag  400  may include body  412 , left upper side  402 , right upper side  404 , zippered top opening  422 , front side  406 , rear side  414 , Velcro section  408  and shoulder strap  410 . Similar to descriptions in previous sections in regards to guitar carrying bag  10  with Velcro section  50  on front side  20  in  FIG. 1  that may be configured to mate with Velcro section  120  on the back side  110  of attachable panel  100  of  FIG. 2 , Velcro section  408  on duffle bag  400  may be configured on left upper side  402  and right upper side  404  of  FIG. 19  to mate with Velcro section  420  on the back side  418  of attachable panel  416  of  FIG. 20 . With Velcro section  420  on the back side  418  mated with Velcro section  408  on the upper sides  402 ,  404  of duffle bag  400 , duffle bag  400  of  FIG. 21  may result. In the depiction of  FIG. 21 , attachable panel  416  may be attached to the general upper sides of duffle bag  400  such that graphical artwork (not shown) may be printed or otherwise affixed to the top side of attachable panel  416  to change the graphical design of duffle bag  400 . 
     As shown in  FIG. 21 , attachable panel  416  may generally cover zippered top opening  422 ; however, attachable panel  416  may include an opening (not shown) that may allow access to zippered top opening. In addition, attachable panel  416  may include divided attachable panels  416  or multiple attachable panels  416  such that one attachable panel  416  may be attached to left upper side  402  and a second attachable panel may be attached to right upper side  404 . In fact, any number of attachable panels  416  may be attached to any number of sides of duffle bag  400  that may or may not cover up zippered top opening  422 . While top opening  422  has been described as utilizing a zipper as attachment means to secure top opening  422  closed, other attachment means such as Velcro, snaps, buckles and other attachment means may be used instead. Also, top opening may not utilize any attachment means and attachable panel  416  may or may not assist in holding top opening closed such that the contents within duffle bag  400  may be secure. 
     It will be obvious to one skilled in the art that all of the variations and different configurations described in earlier sections of this specification in regards to guitar carrying case  10  and backpack  200  in relation to the current invention and how an attachable panel may be configured with guitar carrying bag  100  and backpack  200  may also apply to duffle bag  400  such that these variations and configurations need not be repeated here. 
     In addition to guitar carrying cases and bags  10 , backpacks  200  and duffle bags  300 , there are many additional types of carrying bags and cases that may be configured to include attachable panels and therefore be covered by the current invention. The other types of carrying bags or cases may include purses, luggage, business cases, tablet computer cases, smartphone cases, laptop computer cases, computer cases and other types of carrying bags and cases that may have similar or different shapes compared to the guitar case  10 , backpack  200  and duffle bag  300  described above, and may be designed to carry other types of items compared to a musical instrument case  10 , a backpack  200  or a duffle bag  300 , but may include similar elements as the above described guitar bag  10 , backpack  200  and duffle bag  300  such as front sides, top sides, side sides, attachment means to attach attachable panels, top openings and other elements such that they too may be configured to include an attachable panel. It will therefore be apparent to one skilled in the art that the entire description above of configuring a guitar case or bag  10 , a backpack  200  and a duffle bag  300  with an attachable panel or multiple attachable panels may be applicable to these other types of carrying cases and bags. In addition, these other types of carrying bags and cases may operate in a similar manner with regards to the attachable panel or multiple attachable panels in comparison to the above described guitar carrying bag  10 , the backpack  200  and the duffle bag  300  with regards to the attachable panels, for example but not limited to, how to attach an attachable panel to the carrying bag or case, how to remove an attachable panel from the carrying bag or case, how to retrofit an existing carrying bag or case to receive an attachable panel, and other characteristics. 
     In addition, it will be obvious to one skilled in the art that all of the variations and different configurations described in earlier sections of this specification in regards to guitar carrying case  10 , backpack  200  and duffle bag  300  in relation to the current invention and how an attachable panel may be configured with guitar carrying bag  10 , backpack  200  and duffle bag  300  may also apply to the additional types of carrying bags and cases such that these variations and configurations need not be repeated here. 
     In another embodiment, it may be desirable to provide a means to attach the attachable panel  100  to a carrying bag that may not have been designed and manufactured specifically to receive the attachable panel  100 . In one example of this scenario, a user may already own a guitar carrying bag that may not have Velcro section  50  attached to its front panel  20 . In this case, the means to attach an attachable panel  100  may be provided to the user so that the user may retrofit their existing bag to have the ability to receive attachable panel  100 . This may include providing the user with Velcro fastening material or other fastening means that may be affixed to the front panel of their existing instrument bag that may be aligned and mated with Velcro section  120  on attachable panel  100 . 
     In one embodiment, Velcro loop fastening material or Velcro hook fastening material may be provided to the user in strips, patches, or other patterns that may be attached to their existing guitar bags. The provided Velcro sections may be adhesive-backed such that the adhesive backing on the provided Velcro sections may be used to affix the Velcro sections to the users existing bag. The provided Velcro sections may also have heat-activated adhesive means on the back of the sections such that the Velcro may be attached to the existing instrument bag using a heating device such as an iron or other means. Other means such as glue, pins, clips, latches, sewing means, magnets or other means may also be provide to the user to affix the provided Velcro sections to their existing instrument bags. It may be preferable that the fastening means may come with instructions that may guide the user to properly attach the provided fastening means to their existing instrument bag in such a way that the sections may be fixedly attached in the proper locations such that at least some of the fastening means may align with and mate up with corresponding fastening means, if any, on the attachable panel  100 . In this way the attachable panel  100  may be removably attached to the user&#39;s existing instrument bag as described above. 
     It may also be preferable that the attachable panel  100  that the user may intend to attach to their retrofitted instrument bag may have a generally similar shape and size of the panel of the existing instrument bag that the user intends to attach it to. To these ends, the manufacturer may provide a number of differently shaped attachable panels  100  that may generally fit a significant number of existing instrument bags that may have been sold prior or are currently on the market. The user may then choose the attachable panel  100  that may most closely resemble the size and shape of the panel on their existing instrument bag that they wish to attach the attachable panel  100  to. 
     Also, it may not be necessary that the attachable panel  100  generally resemble the size and shape of the existing bag being retrofitted to receive attachable panel  100 . In one example of this type, attachable panel  100  may only attach to a portion of a panel on the existing bag. In this case, attachable panel  100  may cover only a portion of the panel, for example the front face of the existing bag, and may therefore be any shape. In this embodiment it may be preferable that attachable panel  100  may fit generally within the entire or a portion of the outer contour of the face on the existing bag that it is to be attached to but this may not be required. It may also be preferable that attachable panel  100  not extend past the outer circumference of the face on the existing back to which it is to be attached to, but this also may not be required. In addition, attachable panel  100  may be modified to fit within the contour of the panel to which it may be attached to by folding, cutting or other modification techniques. 
     While the fastening means that may be provided to the user to attach to their existing instrument bag described above include Velcro fastening means, other means may be used to attach the attachable panel  100  to the user&#39;s existing instrument bag such as pins, snaps, clips, latches, zippers or other means. For instance, when attaching attachable panel  100  to an instrument bag that may not have Velcro sections  50 , attachment means other than Velcro fastening means may be utilized. In this application, other means such as clips, pins, snaps, latches or zippers may be provided to attach attachable panel  100  to the existing instrument bag. These alternative fastening means may be attached to the existing instrument bag, to the attachable panel  100 , or to both the existing instrument bag and attachable panel  100  such that attachable panel  100  may be attached to and removed from the existing instrument bag in order to replace attachable panel  100  with another panel of different graphical design. These fastening means may remain on the existing gig bag to receive other attachable panels  100 , may remain on attachable panel  100 , may remain on both the existing gig bag and the attachable panel, or may be removed from the existing gig bag and attachable panel  100  when the panels  100  are exchanged. 
     It should be noted that if the attachable panel  100  may not adequately resemble the shape and size of the panel of the existing gig bag that the user may be retrofitting to receive and attach to attachable panel  100 , means to adjust the size and shape of attachable panel  100  may be provided to the user. These means may include the ability to alter the shape and size of attachable panel  100  by folding, cutting or other means that may alter the shape and size of attachable panel  100 . 
     While the example described above of retrofitting an existing carrying bag that was not originally designed to receive an attachable panel used an instrument carrying bag, specifically a guitar carrying bag, as the example to describe the various elements of the current invention associated with this concept, the elements of the current invention may also pertain to any other type of carrying bag that may be retrofitted to receive an attachable panel. Examples of other types of carrying bags that may be retrofitted to receive an attachable panel may include backpacks, laptop cases, messenger bags, purses, travel bags, business bags, sports bags, duffle bags, luggage and other types of carrying bags and cases. 
     As stated earlier, graphical artwork may be printed on or otherwise affixed to the front panel  130  of attachable panel  100  using a printing machine, a dye sublimation system, silk screening techniques, paint, decals, stickers or other means. 
     In one embodiment, the manufacturer of the instrument bag  10  and attachable panels  100  may offer artwork designs, pictures and other types of graphical files that may be chosen by the user to be printed on front side  130  of attachable panel  100 . In this embodiment, the attachable panel  100  with the design from the manufacturer affixed to its front side  130  may be available for sale in a retail store, in an online store, through an app or in other places. It should be noted that a variety of attachable panels  100  with a variety of different graphical artwork designs printed or otherwise affixed to their respective front sides  130  may be available by the manufacturer for purchase. It should also be noted that the user may have the ability to purchase an attachable panel  100  with a particular design by itself or with the carrying bag  10  that the attachable panel  100  may be attached to. 
     In another embodiment, the manufacturer may provide tools for the user to create their own graphical artwork to have printed or otherwise affixed to the attachable panels  100 . In one embodiment of this type, the manufacturer may provide a website, an app, software or other types of tools that may allow the user to choose different graphical patterns or images, and may provide the ability for the user to position, size, crop and otherwise manipulate or modify these patterns or images within a template that may resemble the shape of attachable panel  100 . The user may then submit the artwork to be printed or otherwise affixed onto an attachable panel  100  to the manufacturer who may print or otherwise affix the artwork to attachable panel  100  and send it to the customer. In addition, the user may perform the above functions without the use of a template that may resemble the shape of attachable panel  100 . 
     In another embodiment of this type, the manufacturer may provide the user with graphical design software that may reside on their website or elsewhere on the Internet, may be provided through the use of a memory device such as a CD, DVD, flash memory device, hard drive memory device or through other means that the user may use to create their own artwork to have printed or otherwise affixed to an attachable panel  100 . The manufacturer may also provide the customer with an app or other types of software tools that the user may use to create their own artwork to have printed onto attachable panel  100 . The manufacturer may also provide a combination of these different types of tools and functionalities, as well as other types of tools and functionalities to the user that may assist the user to create artwork or pictures that may be printed onto an attachable panel  100 . 
     In another embodiment, the manufacturer of the instrument bag  10  and attachable panels  100  may allow the user to provide their own graphical artwork, pictures, logos, or other media files to the manufacturer to be printed or otherwise affixed to the attachable panel  100 . In this scenario, the manufacturer may provide a means for the user to provide to the manufacturer the files to print onto attachable panel  100 . Such means may include the ability to upload the graphical artwork files through a website, or while using an app on a mobile device such as a smartphone or tablet computer, or by sending the files by email to the manufacturer, or by other means such that the manufacturer may receive the files and may print or otherwise affix the artwork to the attachable panel  100 . The manufacturer may also provide an online template, a template computer file, a physical template or other type of template that may resemble the shape of the attachable panel  100  to the user such that the user may overlay their artwork or picture onto the template in order to position, size, crop and otherwise design and edit their artwork to be printed or otherwise affixed to the attachable panel  100 . Other means that may be used to allow the user to provide their own artwork to the manufacturer may include FTP, Cloud computing file storage means, files sent to the manufacturer on physical media storage devices such as flash drives or DVDs, or other means. 
     In addition, means for a customer to upload or otherwise provide the manufacturer of carrying bag  10  with graphical artwork to print or otherwise affix to attachable panel  100  may be provided to the customer at a retail point of purchase of carrying case  10  and attachable panel  100  such as within a retail store or other vendor. In this scenario, the retail store may provide an interactive display that may include an input device that may allow the customer to upload or otherwise provide the graphical artwork or pictures to the manufacturer to print onto attachable panel  100 . The customer may be able to transfer their artwork or pictures from their smartphone, tablet computer, memory device or other type of device to the interactive display such that the interactive display may then provide the artwork or pictures to the manufacturer of attachable panel  100 . Such interactive display may include a tablet computer or other type of input device as well as software, apps or other applications. The retail store may also provide means for the customer to download or otherwise load an app to their own mobile device to use that may allow the customer to transfer the artwork or picture files from their own mobile device or other device to the manufacturer of attachable panels  100 . In addition, the customer may simply download the app from a website or acquire the app from another source in order to use the app to transfer the artwork or picture files to the manufacturer of attachable panels  100 . The manufacturer may then print or otherwise affix the artwork or picture files to the attachable panel  100  for the customer and send it to the customer in the mail, send it to the retail point of purchase for the customer to pick up, or otherwise provide the printed attachable panel  100  to the customer by other means. In this scenario, the customer may have the ability to purchase the carrying bag  10  and the attachable panel  100  from the retail store and may leave the store with the carrying bag  10  with or without an attachable panel  100 , in which case the customer may be provided with the attachable panel  100  at a later time by other means. 
     The interactive display that the customer may use to upload or otherwise provide their artwork or pictures to the manufacturer of attachable panels  100  in order to print or otherwise affix to attachable panels  100  may also keep track of the store and sales information (name of store, location of store, items ordered, total sale value, and other information) such that the store may get credit for the sale of the customized attachable panel  100 . This information may be useful to the manufacturer of attachable panels  100  in order to know the sales performance of the various stores that may be providing this service. This information may also be used to provide payments or incentives to the stores that make the sales for the manufacturer. 
     In another embodiment, artists, designers or other creative types of people may provide their artwork for customers to have printed or otherwise affixed to the front sides  130  of their attachable panels  100 . In this embodiment, an artist may provide artwork to the manufacturer using means similar to described above, and the manufacturer may offer the artwork to their customers to have printed or affixed to the attachable panels  100 . This embodiment may also include a sales commission that may be paid to the artist who may have provided artwork, payable when a customer may choose and order to have that specific artwork printed or otherwise affixed to their attachable panel  100 . In this scenario, commissioned artists may be incentivized to market their attachable panel and carrying bag designs to their own network of fans such that the manufacturer of attachable panels  100  may also benefit from this marketing. Artist may also receive for hire payments without a sales commission, or a combination of for hire payments and sales commissions. 
     In yet another embodiment, companies or other entities may provide the manufacturer of the carrying bag  10  and attachable panel  100  with artwork that may be printed or affixed to the attachable panels  100  that may be used for advertising or marketing purposes. That is, a company may provide graphical artwork to the manufacturer of the instrument bag  10  and attachable panel  100  that may advertise the company&#39;s products or services in an aesthetically pleasing way such that a user may wish to have the graphical advertisement printed or affixed to an attachable panel  100  that may be affixed to their carrying bag  10 . In this way, the user may carry the bag for others to see, and the advertisement printed on the front side  130  of the attachable panel  100  on their carrying bag  10  may provide valuable advertising for the company. In this embodiment, the company providing the advertisement graphical artwork may not only provide the artwork to the manufacturer of the bag  10  and attachable panel  100 , but may also pay the manufacturer an added fee for providing the advertising means. 
     As stated above, graphical artwork may be printed or otherwise affixed to attachable panel  100 ,  208 ,  308  using a variety of techniques such as hand painting, silk screening, dye sublimation and other techniques. 
     In the case of dye sublimation, the artwork may first be printed onto paper using a dye sublimation printer. The graphical artwork may then be transferred from the printed paper to the attachable panel  100 ,  208 ,  308  by placing the paper face down onto the side of the attachable panel  100 ,  208 ,  308  that may receive the artwork, and then pressing the artwork paper and attachable panel  100 ,  208 ,  308  together at an elevated temperature and at a desired pressure to effectively melt the ink on the artwork paper and transfer the graphical image to attachable panel  100 ,  208 ,  308 . It may be preferable that attachable panel  100 ,  208 ,  308  be made of a high percentage of Polyester such that the dye sublimation process may be more effective. 
     However, this dye sublimation process may be typically designed to work with transferring graphical images from printed artwork paper as described above to a nominally flat substrate such as a flat piece of Polyester canvas, a flat sheet of metal, a flat piece of wood, or other nominally flat substrates. The reason for this is that the dye sublimation process may be most effective in producing a consistent and well printed image when there is even and constant pressure and temperature applied across the entire printed paper and substrate combination. 
     In the case of attachable panel  100 ,  208 ,  308 ,  416  the standard dye sublimation process may have a problem uniformly transferring the graphical images printed on the artwork paper to attachable panel  100 ,  208 ,  308 ,  416  due to Velcro section  120 ,  218 ,  408  that may be sewn onto attachable panel  100 ,  208 ,  308 ,  416 . Velcro section  120 ,  218 ,  420  that may be sewn onto attachable panel  100 ,  208 ,  308 ,  416  may cause attachable panel  100 ,  208 ,  308 ,  416  to not be nominally flat, but instead may cause attachable panel  100 ,  208 ,  308 ,  416  to have raised sections due to Velcro section  120 ,  218 ,  420  in the areas where Velcro section  120 ,  218 ,  420  may be sewn onto attachable panel  100 ,  208 ,  308 ,  416 .  FIG. 22  depicts this for the case of attachable panel  100  looking in the direction of arrows C of  FIG. 2 . This in turn may cause the dye sublimation process to have uneven pressure and temperature across the entire surface of attachable panel  100 ,  208 ,  308 ,  416 , specifically in the areas immediately surrounding the raised areas that may be due to Velcro section  120 ,  218 ,  420 . In this case, the image being printed onto attachable panel  100 ,  208 ,  308 ,  416  may have inconsistencies in these areas. It should be noted that it may be preferable that Velcro section  120 ,  218 ,  420  be sewn onto attachable panel  100 ,  208 ,  308 ,  416  before the dying process such that the thread or other means used to sew or otherwise affix Velcro section  120 ,  218 ,  420  to attachable panel  100 ,  208 ,  308 ,  416  may be covered by the graphical artwork that may be printed onto attachable panel  100 ,  208 ,  308   416 . It may be preferable that if thread may be used to sew Velcro section  120 ,  218 ,  420  to attachable panel  100 ,  208 ,  308 ,  416 , that the thread may be Polyester thread such that the dye sublimation process may print more effectively on the thread. If Velcro sections  120 ,  218 ,  420  were sewn onto attachable panel  100 ,  208 ,  308  after the graphical artwork was transferred to attachable panel  100 ,  208 ,  308 ,  416 , the thread may cover up the artwork that may have been printed onto attachable panel  100 ,  208 ,  308 ,  416  in the areas where the thread may have been used to sew Velcro section  120 ,  218 ,  420  to attachable panel  100 ,  208 ,  308 ,  416  which may be unsightly and less preferable. 
       FIG. 23  depicts one embodiment that may solve this dye sublimation problem of attachable panel  100 ,  208 ,  308 ,  416  having raised sections as described above. As shown in  FIG. 22 , a soft pad  400  may be placed underneath attachable panel  100 ,  208 ,  308 ,  416  with Velcro section  120 ,  218 ,  420  resting against the top surface  402  of pad  400  such that when pressed with printed artwork paper as described above at a desired pressure and elevated temperature, Velcro section  120 ,  218 ,  420  may be pressed into top surface  402  of pad  400  and may create small indentations  404  in top surface  402  of pad  400 . This may effectively allow top surface  130  of attachable panel  100 ,  208 ,  308  to be nominally flat such that the pressure and temperature may be more consistent across the entire top surface of attachable panel  100 ,  208 ,  308 ,  416  such that the dye sublimation process may be more effective resulting in a higher quality graphical image. 
     Because each attachable panel  100 ,  208 ,  308  may be printed individually and then configured onto a carrying bag as described above, the manufacturer of carrying bags with attachable panels may not need to hold inventory of any particular graphically designed attachable panel. That is, the manufacture may only need to carry inventory of carrying bags that may be configured to receive and be configured to an attachable panel, and blank ready-to-print attachable panels that may be configured to the carrying bags. Note that the manufacturer may carry inventory of a single type of carrying bag along with attachable panels that may be configured to fit onto the single type of carrying bag, or the manufacturer may carry inventory of multiple types of carrying bags along with multiple types of attachable panels, with each type of attachable panel configured to fit onto its respective particular type of carrying bag in inventory. Then, upon an order from a customer for a particular type of carrying bag with an attachable panel containing a particular graphical design on the attachable panel, the manufacturer may print the desired particular graphical design onto the applicable blank attachable panel made for the type of carrying bag being ordered by the customer, mate the attachable panel that has been printed with the desired graphical design to the ordered carrying bag, and ship the ordered carrying bag with the mated attachable panel containing the desired graphical design to the customer. 
     This is in stark contrast to printing graphical designs directly onto a permanent side or multiple permanent sides of a carrying case, in which scenario the graphical designs may be a permanent element of the carrying case. In this scenario of permanent designs printed onto permanent sides of a carrying case, the manufacturer of such carrying cases may need to carry inventory of said cases as it may not be possible or financially feasible to create each carrying case individually with particular graphics on permanent sides of the carrying case. In most cases, manufacturers of carrying cases may have a minimum order quantity requirement of hundreds if not thousands of units of a particular design in order to be able to produce the product at a reasonable cost. Producing higher volume of identical graphical designed units may result in a lower and more reasonable cost per unit, and because of this, a factory may only manufacture orders of a particular graphical design if the quantity ordered is at least the minimum quantity required. This may force a manufacturer that wishes to sell carrying bags with permanent graphical sides to produce the minimum order quantity of a particular graphical design or designs in hopes that these graphical designs will be popular and will sell through. 
     If a manufacturer is forced to carry inventory on carrying bags with permanent graphics printed onto permanent sides of the carrying bags, the manufacturer may be at risk of the bags not being popular and not selling, or of the graphical designs falling out of popularity before the entire inventory of a particular graphical design has been sold. In these cases, the manufacturer may be forced to liquidate the unsellable inventory at a financial loss. 
     However, because the manufacturer that wishes to sell carrying bags with attachable panels does not need to carry inventory of a particular graphical design to be printed onto the attachable panels, the company in this scenario does not need to produce minimum quantity orders of a particular graphical design. The company only needs to produce minimum order quantities of the carrying bags configured to receive attachable panels as described above, along with minimum order quantities of blank ready-to-print attachable panels. Since these carrying bags may not contain any graphics on them, they are not in danger of falling out of style due to a graphical design, and the manufacture may not be forced to liquidate them at a financial loss. 
     In fact, the manufacturer of carrying bags or cases with attachable panels is able to produce particular graphically designed carrying bags and cases that may be popular on one day, and upon those graphical designs falling out of popularity, may be able to produce new and entirely different graphically designed carrying cases and bags on another day simply by choosing a new digital artwork file to print. Because the graphical designs may be digital artwork files on a computer that may be printed onto blank attachable panels whenever desired, an entire library of designs may be created and offered to the public for sale, and then printed onto blank attachable panels when ordered by a customer without having to ever carry physical inventory of any of the printed designs. This may eliminate significant financial risk compared to having to carrying physical inventory of any carrying bags with permanent graphical designs. 
     In addition, as described above, customers may design their own graphical designs to be printed onto the attachable panels. By producing carrying bags and cases with attachable panels instead of carrying bags with permanent graphical designs on permanent sides of the carrying case, the manufacturer may be able to print the customer&#39;s graphical design onto the attachable panel, configure the printed attachable panel onto the desired carrying bag and fulfill the order to the customer at a reasonable cost. In this scenario, the customer&#39;s graphical design may be a digital file similar to any other digital file that the manufacturer may have of any other graphical design, and thus may be printed onto a blank ready-to-print attachable panel upon the customer&#39;s order. This manufacturing process is sometimes referred to a “just in time manufacturing” or “to order manufacturing”. Conversely, if the manufacturer were manufacturing carrying bags with permanent graphics printed onto permanent sides of the carrying bags, it may not be possible or financially feasible for the manufacturer to print the customer&#39;s designed graphics onto the permanent sides of the carrying bags at a reasonable cost. 
     As described above, the sales revenue methods of the present invention may include online sales of carrying bag  10  and attachable panel  100  either together or separate, brick-and-mortar retail store sales of instrument bag  10  and attachable panel  100  either together or separate, selling in-house designed attachable panels  100 , selling attachable panels  100  designed by other artists, selling attachable panels  100  with designs created by customers, selling attachable panels  100  with designs created by customers using tools provided by the manufacturer, selling advertising space on the attachable panels, and other methods. 
     The present invention includes a number of aspects and features which may be practiced alone or in various combinations or sub-combinations, as desired. While preferred embodiments of the present invention have been disclosed and described herein for purposes of illustration and not for purposes of limitation, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
