A few things I thought could make better duct tape wallets.
1: Buss-Pass/ I.D. Pocket,
Perhaps a pocket made out of clear packing tape that covers the whole card could be used for I.D. or a Buss-Pass.
2: Coin Purse,
A Sideways-facing pocket can be made to fold-out sideways from the wallet, when the pocket is folded-in, It acts like an envelope and keeps the coins in.
3: Dividing Page,
A properly sized page taped on the inside "spine" of the wallet could be added to allow for more compartments.
4: Transparent/ Clear Carcass,
The Carcass of the wallet could be made with clear packing tape or transparent duct-tape
5: Sports-Grade Grip-Tape/ Hockey Tape Parts,
Parts of the wallet could be made from Grip-Tape or Hockey Tape, These products can be found in black, colors or transparent.
