For this project, I used my textured 12X12" card stock. You need 4 1/4" X 11" for the wallet base. I scored my wallet @ 3", 3 1/4", 7 1/4" and 7 1/2". For the inside, 4 X 12 scored @ 4" and 8". I added more paper to add onto the length. I think you don't have to. Especially if you put photo's on both sides. I used the DSP Outlaw and the SSK Round Up, both by Stampin' Up!
I used the scallop punch with a jumbo eyelet for a closure. The hemp is just wrapped around the wallet, then wrapped under the eyelet. Holds it perfect.
