Below is the wallet template with cash strap designs. There isn't a big difference between 7.0 and 7.1 except for the addition of a 2/8'' seam to hide raw edges. I'll see if I can make this into a printable free template.
When you trace this template, I would strongly suggest cutting inside the pen markings as it will give you the tightest fit for your cards. This template will hold 8-9 cards comfortably.
