Step 1: The Beginning
Fold the bottom part of the paper about an inch so it covers about 1/3 of the credit card.
Step 2: The Folding
Turn the paper over and line up the first fold with the bottom of the paper, then fold the opposite part of the paper (the side that hasnt been folded yet) into the others, so you can see 3 'steps'.
Step 3: The Cutting
Fold all but the bottom into the pocket that has been made on the side of the wallet.
Then fold the last piece of paper so it is with the others. Repeat on both sides.
Step 4: The Final Fold
