Step 1: You'll Need...
Duck tape, credit card, and a (duck tape) wallet that has no or little card pockets.
Step 2: Make The Pocket
Cut a strip of duck tape an inch longer than your card. Make another strip as long as your card. Attach them so you have an even amount of sticky on each side. Make a tiny strip as long as the whole pocket. Put it on the bottom so there's sticky on the same side, on three sides of your pocket.
Step 3: Stick It On
Put the pocket on to your wallet and stick. That's it! Make more to put on, add your cards and close it up! Favorite, comment, and follow! Thanks!
