Hi guys, this card wallet is just an experiment following Phil video on making slots using ripstop nylon using glue template. How thin is the limit for making the leather slots, the front most pocket as well as the back. In the photo, the back is 0.5mm, the slots is 0.5mm (folded 1mm), the front most pocket is 0.7mm. Should i go thinner than this and using reinforcement tape?
