How to make an easy, fast, and durable (depending on the type of tape you use) duct tape wallet (yes, I know that there are other duct tape wallet designs on Instructables, but I wanted to add my design to the myriad of other duct tape wallet designs).
P.S. Here are some other duct tape wallets on this site
Step 1: Materials
You will need: tape (the tougher the tape, the tougher the wallet), scissors, a ruler, and a hobby knife.
Step 2: Begin to make the back and the billfold piece
Cut 4 pieces of 8.5 inch long tape (as shown in step 1) and put the strips together in pairs as shown below so that the strips are 8.5 inches long by 3.5 inches wide.
Step 3: Finish the back and the billfold piece
Take the two pieces of 8.5 by 3.5 tape and put the two sticky sides together to make a sort of "tape fabric" as shown below. Repeat this step to make the back of the wallet. For the back of the wallet, if the tape that you are using is not very thick, you may want to make the back twice as thick as the billfold piece. Both the back and the billfold pieces are shown in the second picture on this step.
Step 4: Create the pieces for the card pockets
First, cut off two pieces of 4 inch long by 2 inch wide tape. Second, cut off 2 pieces of 4 inch long by 1.5 inch wide tape.
Finally, stick the two pieces of 4 inch by 2 inch together to make tape fabric. Then do the same with the 4 inch by 1.5 inch tape.
Step 5: Make the piece to hold a card so that it is visible when you open the wallet
First, make a 4 inch long by 2.5 to 3 inch piece of tape fabric.
Then, cut out a piece of the tape fabric that is a bit smaller than the card you want to put in it so that the card won't fall out. Make sure that the top of it is open so you can slide the card in and out easily. The finished product should look like the piece in the picture below.
