REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application is a Continuation-In-Part of U.S. Design application Ser. No. 29/509,502, filed Nov. 18, 2014, entitled “Combination Flat and Fitted Bed Sheet,” which is hereby specifically and entirely incorporated by reference. 
     
    
     BACKGROUND 
       [0002]    1. Field of the Invention The invention is directed to sheet sets. In particular, the invention is directed to sheet sets with attachment devices to maintain the arrangement of the sheets during use. 
         [0003]    2. Background of the Invention 
         [0004]    Bed sheet sets typically come with a fitted sheet and a flat sheet. Sheet sets may additionally include one or more pillow cases. The fitted sheet fits over the mattress or a mattress pad. Typically, a fitted sheet is comprised of a flat portion that sits on top of the mattress and side panels that envelope the sides of the mattress. The side panels may have elastic portions along the edges to help secure the fitted sheet to the mattress. The fitted sheet may also be secured using a drawstring instead of elastic or another fastening device. The fitted sheet is preferably secured from slipping off the mattress while the bed is in use. Flat sheets are typically square or rectangular pieces of material that sit atop the fitted sheet and may be tucked around the fitted sheet and under the mattress. Additionally, blankets or comforters may be used on top of the sheets to provide extra warmth. Beds and their corresponding bed sheets come in a variety of sizes to accommodate one or more people. Some common sizes include Twin (39″ wide×75″ long), Twin Extra Long (“Twin XL”) (39″ wide×80″ long), Full (54″ wide×75″ long), Queen (60″ wide×80″ long), and King (76″ wide×80″ long). Additionally, smaller size beds, such as cribs, are made for infants and children. However, beds can come in other shapes and sizes. Often with custom sized and shaped beds custom sized and shaped sheets need to be made. 
         [0005]    During use of a bed, the sheets and blankets may become disarrayed and the bed needs to be remade. Remaking of the bed may entail removal of the top sheet and any blankets to make sure that are properly replaced on the bed for the next use. Proper placement may include positioning the head edge of the sheet at the head of the bed (the portion of the bed where a user typically places their head), positioning the foot edge of the sheet at the foot of the bed (the portion of the bed where a user typically places their feet), and ensuring that the correct side of the sheet is facing up. Such rearranging of the sheets and blankets is time consuming. Furthermore, when washing the sheets, the sheets typically separate and it is difficult and time consuming to properly rearrange the sheets for placement on the bed. Therefore, there is a need for a device that can easily maintain the arrangement of the sheets during use of the bed and during washing. 
       SUMMARY OF THE INVENTION 
       [0006]    The present invention overcomes the problems and disadvantages associated with current strategies and designs and provides new devices and systems to properly maintain the arrangement of sheet sets. 
         [0007]    One embodiment of the invention is directed to a sheet set. The sheet set comprises a fitted sheet adapted to be placed over a mattress, a top sheet adapted to be placed atop the fitted sheet and having a first width, a sheet extension extending from a first edge of the top sheet and having a second width, wherein the second width is shorter than the first width, and at least one fastening device adapted to couple the top sheet to the fitted sheet. 
         [0008]    In a preferred embodiment, the at least one fastening device is a button coupled to a foot of the fitted sheet and is adapted to engage a button hole in the sheet extension. Preferably, the at least one fastening device is a button coupled to the sheet extension and is adapted to engage a button hole in a foot of the fitted sheet. Preferably, the at least one fastening is adapted to engage both a button hole in a foot of the fitted sheet and a button hole in the sheet extension. 
         [0009]    The sheet set preferably further comprises a cutout on each side of sheet extension and adapted to allow the top sheet to lay flat on top of the fitted sheet. In a preferred embodiment, the top sheet lays flat without bunching or overlapping in the corners. The at least one fastening device preferably only couples a foot of the fitted sheet to the sheet extension. The sheet set preferably comprises a securement device coupled to one or more edges of the fitted sheet adapted to secure the fitted sheet to the mattress. Preferably, the top sheet, without the sheet extension, has a length equal to a length of the mattress. Preferably, the at least one fastening device is positioned along a foot side of the mattress. In a preferred embodiment, the sheet extension has a length equal to the depth of the mattress.
