Here's my first duct tape wallet, I'm not 100% happy with it but its not bad for my first go.
It took me a few hours to make as I'm not used to working with duct tape but I was pleasantly suprised that I only had a few wrinkles in it so I hope the next one turns out even better.
This is the inside, it has 4 card holders, an ID holder and a space for money (notes), I hope to try and add a small coin purse to the next one but I still need to design that one :)
