So I know there are already a bunch of these but here is my easy duct tape wallet. I made this for my teen Summer Reading Program at my library.
You will need
Duck tape, any colors (I'm using three different colors to show the parts easier)
Gift card or credit card to help measure
Step 1: Create a Piece of Duct Tape Fabric
Cut 4 pieces of tape, about 10" long, and lay them on the work surface, sticky side up. Connect them by overlapping the top edge of one to the bottom edge of the next. Repeat with remaining two pieces of tape. Now you have a sticky square.
