I just had to do a display last week for my booth. I sell a large variety of items so I got a "bin" that is 8.5 x 8.5. my widest decal is 8". I used black matboard as dividers between each design and I put the decal on the black to show clearly how it will look on glass. At the top I put the name of the decal and its price. Now customers can flip through the display looking at all the designs and then reach in behind to get the one(s) they want. I took pictures of what the vinyl looks like on the mat board, but they are at home now, I will post a few tonight. One could also buy smoked plex in a large sheet and put a bunch of decals on it. I am thinking of doing that for next year and it can lean, or hang up below the decal box.
