UPDATE! I added a little spot for my Blutooth dongle I bought. I don't have instructions right now, but you just add a smaller pocket in between the bigger pockets.
Step 1: Materials
-tape measure or ruler(handy, but optional)
-and, of coarse, usb sticks/thumb drives! (fun stuff)
Step 2: Make One Big Slab-o-duct Tape! :)
-First, pull two foot long duct tape pieces from the role,cut em, and lay them side by side on the table(fig #1 & #2).
-Then, pull another strip of duct tape about 2 inches longer than the other two duct tapes(the extra length will hold the slab in place for now), and lay it on the other two duct tapes(fig #3 & #4).
-After, cut one more foot long piece, cut it in half all the way down, and place each piece over one of the ends(fig #5, #6 & #7).
-Lastly, lift it from the table, and trim all the edges(you can throw the clippings away, unless you want to keep them :P) (fig #8 & #9).
Step 3: Add Pockets
-First, you need to decide how big you want it, then trim it to that size(I suggest that you leave a 1 inch gap between were you want it to fold, so that it folds easier). And decide what type of layout to use. Fig #1 shows how big I decided it to be, and my layout.
-Now, for the pockets. First, cut two strips of duct tape a little longer then the usb stick/thumb drive, and put them face down on the wallet/holder. I can't really explain this well, so look to the picture for reference(fig #2). Then, fold the pieces of duct tape over and stick them together on them selfs to create the general shape of the pocket(I had to trim mine)(fig #3). After, put a piece of duct tape over the pocket to make it look neat(I put two on mine)(fig #4 & #5).
-Now, continue to make the pockets where you want them to be! Then you will be almost done! :D(fig #6)
Step 4: Finishing Up!
One thing you can do is put a couple pieces of duct tape on the back to make it smother(fig #1 & #2). You could also make it in deferent colors, put more pockets on or not make as many, or make a picture of something on the back with duck tape! Hope you liked this instructable! I got the pattern for the pockets and the slab-o-duct tape from dan MonkeyLectric and his instructable on how to make a duct tape wallet; https://www.instructables.com/id/quality-duct-tape-wallet/
