         [0026]    In some implementations, a panel can have an outer surface comprising a solid material (e.g., a white board, a monochromatic fabric, a metal, etc.). The solid surface may permit a user to create customized drawings or text by means of using a permanent pen, highlighter, crayon, marker, or other writing implements. For example, and without limitation, a panel can include a dry erase board permitting a user to decorate the panel with markers. In other non-limiting implementations, a panel may be magnetic, allowing different decorative magnets to be added thereto. In further non-limiting implementations, a panel can include an outer sleeve or pouch through which a printed drawing, photograph, sign, symbol, award, artwork, and the like can be inserted. It is to be appreciated that in such implementations, a user can print their own decorative drawings or artwork (for example by using a personal computer and printer), and insert the personal decorative work in the sleeve or pouch. In other non-limiting embodiments, the sleeve or pouch may contain a kit for different activities with special compartments and elements therein. As an example and without limiting the invention, the pouch may comprise a make-up kit with a mirror fixed therein and special slots for brushes, lipstick, etc. In some other non-limiting embodiments, the pouch may comprise games, such as connect-the-dot games, doll dress-up games, and mazes. It is to be appreciated that in some of such embodiments, the sleeve can be opaque and impermeable permitting a user to write on the sleeve. In some other of such embodiments, a ferromagnetic game board may be inserted in the sleeve and magnetic game pieces can be placed on the outside of the sleeve for magnetic engagement there through to the game board. 
         [0027]    In some implementations, a panel can have an outer surface comprising a canvas to enable a user to decorate the panel with a user&#39;s art. In some examples, and without limitation, the canvas can be decorated with writing implements (e.g., crayons, markers, pens, etc.) paint, iron-on decals, sewn monograms, sewn badges, autographs, beads, mosaic inlays, lapel pins, buttons, laminate, metal, glass, clocks, shells, basket weave, laminates, embroidery, needlework, cross stitching, crochet, knitting, stencils, maps, tie-dye, airbrushed art, silkscreen collages, and combinations thereof. It is to be appreciated that other user configured decorations and artwork are contemplated in accordance with some embodiments of the present invention. In some implementations, advertisements, or displays for licensed and unlicensed designs, patterns and/or logos, can be included on the outer surface of the panels. In other non-limiting embodiments, the outer surface of the panel may be covered with a fabric having fine loops and patches having fine plastic hooks may be engaged with the loops of in the outer surface of the panel (e.g., Velcro patches). For example, and without limitation, patches bearing logos, sports teams, slogans, etc. may be easily detachably engaged to the outer surface of the panel. In still other non-limiting embodiments, the panel may have hooks, snap buttons, or other fasteners on its outer surface for attaching charms, decorative chains, pinwheels, flowers, bows, figurines, dolls (e.g., stuffed dolls or animals), and other decorative items. 
         [0028]    In some non-limiting embodiments, other items may be engaged with the fasteners on the base bag. For example, decorative elements such as decorative button caps, charms, bows, pinwheels, figurines, etc. may be attached to one or more of the fasteners on the base bag. The base bag may have female or male snap button fasteners on its outside surface, and the decorative elements may have complementary snap button fasteners, allowing the decorative elements to be attached to the base bag instead of a panel. Other decorative items may be engaged with the base bag fasteners, as well. For example, and without limitation, dolls (e.g., baby dolls, stuffed animal dolls, celebrity dolls, etc.) having fasteners in each of four limbs (e.g., in the hands and feet) may be attached to the base fasteners. In other embodiments, the fasteners on the base bag may be engaged with hooks, ties, or other means for attaching items to the base bag, such as ornaments, figurines, stuffed animals, or other items. 
         [0029]    In some non-limiting embodiments, the panels may themselves be reversible and may have decorative features on both sides thereof. As an example and without limiting the invention, the panels may have fasteners on both sides of the panel to allow either side of the panel to be attached to the base bags. In a non-limiting example, the panels may have a slot in each corner for receiving a button head on a corresponding portion of the base bag. In another non-limiting example, the panels may have female snap button fasteners on both sides of the panel, the fasteners on each side of which may correspond to male snap button fasteners on the outside of the base bags. Alternatively, the panel may have male snap button fasteners on both sides of the panel for female receivers on a corresponding portion of the base bag. The panels may also have decorative snap button caps for disguising the snap button female or male parts that are on the outer exposed side of the panel. For example, and without limitation, a decorative snap button cap may include a fabric flower having a fastener on a back surface thereof. Without limiting the invention, the snap button caps may be engaged with the outer snap button fastener, thereby adding a decorative element to the panel while simultaneously concealing the fasteners on the outer exposed surface of the panel. The decorative element may be decorative button caps, charms, bows, pinwheels, flowers, etc. In a further non-limiting example, the panel may have snap button fasteners that are mounted on a reversible axial joint that allows the snap button fastener to spin in the joint and be engaged from either side of the panel. For example, the snap button fasteners on the panel may have female fasteners on one side and a decorative design and/or material on the other side. 
         [0030]    It is appreciated that other panels are contemplated in accordance with some embodiments of the present invention. In some non-limiting examples, a panel can include an electronic device, lights (e.g., LED lights), or electronic displays (e.g., LED, OLED, or LCD screens) to display images or video. For example, the panel may have a decorative pattern (e.g., wording, an animal, a symbol, and other images) of lights that may be lit in various patterns (e.g., all the lights may be activated simultaneously, the lights may be activated in a cascading pattern, etc.). The panel may also be operable to activate the lights in multiple preprogrammed patterns that may automatically alternate in a sequence or the panel may have a switch for selecting the desired, pre-programmed pattern. In other non-limiting embodiments, the panel may include an LED screen operable to receive digital data from a memory device (e.g., a thumb drive), and provide a display of photos (e.g., scrolling photos) or video on the panel. The panel may include other electronic devices such as a calculator, or solar panels for a charger. In one non-limiting example, the panel may have small solar panels on the outside and a pouch therein having a plug for charging an electronic device, such as a smart phone, a tablet, a camera, and/or a digital music player. In other non-limiting examples, a panel can be formed of plastic, beads, mosaic inlay, metal trim, glass, clocks, shells, and combinations thereof. 
         [0031]    It is to be appreciated that, in some preferred embodiments, the panels can have a particular style of fabric that serves as a unique decorative element. For example, and without limitation, the panels can be constructed or comprise cotton, silk, cork, cashmere, plastic, acrylic, corduroy, felt, elastane (e,g, spandex), suede, velvet, paper, corkboard, fur, faux fur, leather, suede, wool, linen, hemp, ramie, jute, lastex, nylon, polyester, rayon, pleather, feathers, mesh, wood, chain link, rhinestones, semi-precious stones, garland, sequins, and combinations thereof. 
         [0032]    Exemplary Fasteners 
         [0033]    In preferred embodiments, an inner surface of the decorative outer panels may have fastening elements for cooperating with complementary fastening elements on the base bags. In some implementations, the fastening elements comprise snaps or buttons. However, it is to be appreciated that other fastening elements are contemplated in accordance with some embodiments of the present invention. For example, and without limitation, the fastening elements may comprise fabric hook-and-loop fasteners, magnets, eyelets, eyeholes, hooks, loopholes, chain links, chains, zippers, pegs, grommets, ribbons, or knots. It is to be appreciated that fabric hook-and-loop fasteners may be complementary fasteners having a first side that is made up of semi-rigid hooks and a second side made up of soft fabric loops (e.g., Velcro). When the two sides of the hook-and-loop fasteners are brought together the hooks engage with the loops and hold the two sides together. The hooks may be made from a plastic material such as polyester or polyethylene, and the loops may be made from thread comprising polyester, polyethylene, polyamides, wool, or other thread materials. 
         [0034]    It is to be appreciated that the location of the fastening elements on the panels should correspond to the location of the fastening elements on the base bags, such that the panel can be affixed to at least one side of the base bag. In preferred embodiments, a system can include a plurality of panels and a plurality of base bags, where the fastening elements of the base bags and the fastening elements of the panels are in the same locations. Without limiting the invention, the system may be based on a single, universal pattern of fasteners having a regular spacing and number of fasteners. As a non-limiting example, the system may be based on a pattern of four fasteners arranged in a rectangular pattern, such that the fasteners are near the corners of a rectangular shape of the panels. Each type of bag (e.g., a handbag, a purse, a tote, a technology case, a lunch box, etc.) may have corresponding fasteners arranged in the same pattern on one or more sides, surfaces, or sections. For instance, a handbag may have a front section (and/or a back section) that is same size as the panel, and may have fasteners placed at the corners of the front and/or back sections for attaching the panel thereto. In other instances, and without limitation, a clutch bag may have fasteners arranged on a front and back side such that some fasteners of a single panel may engage the fasteners of the front side of the bag and some other fasteners of the panel may engage the fasteners of the back side of the clutch. As such, a single panel can be affixed to multiple types of base bags, and multiple panels can be affixed to a single type of base bag. In other non-limiting embodiments, the system may be based on a different pattern of fasteners, such as a triangular pattern, a star pattern, a circular pattern, an oval pattern, polygonal patterns, and other geometric patterns. 
         [0035]    In some embodiments, the fastening elements of the panels can be affixed to an inside surface thereof. For example, and without limitation, the fastening elements can comprise fabric hook and loop fasteners sewn into the inner surface of the panel. In some embodiments, the fastening elements can extend through the panel. For example, and without limitation, the fastening elements can comprise snaps which have distal connecting ends on an inside surface of the panel and proximal cosmetic ends on an outside surface of the panel. It is to be appreciated that in some embodiments a proximal end of the fastening elements are exposed at an outer surface of the panels. Accordingly, the fastening elements may also comprise decorative elements. For example, and without limitation, the fastening elements can have decorative elements on proximal ends thereof with distinctive styles, colors, logos or other visual art which may be exposed on the outside surface of the panel. As explained above, in some embodiments the fasteners may be reversible, such that they may be reversed with panels that may have patterns or other features on both sides thereof. As a non-limiting example, the fasteners on the panel may be reversible female components of snaps that can be rotated 180° to allow the panel to be attached to the base bag with either side of the panel exposed. 
         [0036]    In some embodiments, decorative elements can be engaged with the fastening elements on the base bag. For example, and without limitation, decorative buttons can be engaged with one or more fastening elements on the base bag. In some embodiments, decorative elements can be engaged to an outside surface of the panels. In some implementations where the fastening elements extend through the panel, the decorative elements can be engaged to the proximal end of the fastening elements. However, in some implementations, decorative elements can be engaged to other portions of the panels. In some implementations, the decorative elements may comprise a charm. However, it is to be appreciated that other decorative elements for attachment to the panel and/or base bag are contemplated in accordance with some embodiments of the present invention. For example, and without limitation, the decorative element may comprise buttons, bows, pinwheels, or stuffed toy animals or other toys. 
         [0037]    Exemplary Systems 
         [0038]    Referring now to the exemplary illustrations, a system can include a plurality of base bag types to which one or more of a plurality of interchangeable panels may be affixed. Each of said base bag types may have a different structure, such as a handbag, a purse, a tote, a technology case, a lunch box, etc.) In some preferred embodiments, a single panel may be affixed to a plurality of base bags. In such embodiments, and without limitation, a plurality of base bags and a plurality of panels may share a universal pattern of fasteners and a single kind of fastener system (e.g., snap buttons), allowing each of the plurality of panels to be affixed to any of the plurality of bags. For example, and without limitation, the panel of  FIG. 1  may be configured to be attached to the base bag of  FIG. 1 , the base bag of  FIG. 4 , or the base bag of  FIG. 5 . However, it is to be appreciated that other panel/base bag configurations are contemplated in accordance with some embodiments of the present invention. 
         [0039]    In some preferred embodiments, the type and placement of the fastening elements on the panels and base bags are standardized such that any panel in the system may be attached to any base bag in the system. However, it is to be appreciated in accordance with some embodiments of the present invention, a system may comprise base bags and panels each having different shapes, sizes, and fastening elements. It is further to be appreciated that (i) the size of a panel and the type and placement of the fastening elements thereon and (ii) the size of the base bag and the type and placement of the fastening elements thereon, may provide for various base bag/panel combinations. For example, and without limitation, a system may include (a) a first and second panel, with first and second sizes and fastening element types, respectively, (b) a first base bag adapted to receive the first or second panel, (c) a second base bag adapted to receive the first panel, and (d) a third base bag adapted to receive the second panel. In such embodiments, the decorative, functional, and reversible features of the panels (as described above) may apply to panels of different sizes and shapes. It is to be appreciated that other variations are contemplated in accordance with some embodiments of the present invention.

In other non-limiting examples, the panel  80  may have a fabric hook and loop system for attaching patches (e.g., school-related patches, sports-related patches, etc.). In further non-limiting examples, the panel  80  may have an LCD screen operable to show digital photos or videos. 
         [0047]    It is to be appreciated that, in preferred embodiments, the spacing of fastening elements  1 A- 1 D,  2 A- 2 D,  3 A- 3 D,  4 A- 4 D,  5 A- 5 D, and  6 A- 6 D, on panels  10 ,  20 ,  30 ,  40 ,  50 , and  60 , respectively, are similar such that each panel may be attached to any base bag in a system. Correspondingly, it is to be appreciated that, in preferred embodiments, the spacing of fastening elements  1   a - 1   d ,  2   a - 2   d ,  3   a - 3   d ,  4   a - 4   d ,  5   a - 5   d , and  6   a - 6   d , on base bags A, B, C, D, E, and F, respectively, is universal, such that each base bag may receive any panel in a system. 
         [0048]    In some embodiments, a panel may be attached to a base bag by engaging each fastening element on the panel to each fastening element on the base bag. For example with reference to  FIG. 7 , and without limitation, panel  90  may include more than four fastening elements (e.g., nine fasteners) for engaging each more than fastening elements (e.g., nine fasteners) on base bag G. However, it is to be appreciated that in other embodiments of the present invention, less than all fastening elements may be used. For example with reference to  FIG. 8 , and without limitation, panel  100  may include four fastening elements for engaging four of the nine fastening elements on base bag G. It is further to be appreciated that, in some embodiments, multiple panels may be attached to a single base bag. For example with reference to  FIG. 9 , and without limitation, panel  110  and panel  120  may each be attached to base bag G.
