All you need is: paper (8.5-11), I-pod nano or other small mp3 (I have only tried with Ipod), some clear package tape and some thing to cut out the button/screen holes. The full paper wallet with Ipod is a little less thick then empty leather wallet.
Step 1: Measure and fold
1 Fold in half
2 Measure money size, line up dollar on left side of paper with non folded end facing down, fold bottom edge up and make sure a dollar will fit.
3 measure Ipod/mp3 align to right side fold
4 fold left side so it align with the right side
As I said look at pictures.
