These files will make a leather wallet with 2 card pockets and slot for cash. You will need 2-3 oz leather (1-1.5mm thick), and some thread. You will also need the slide extension if you are using the F1.
I recommend a 2-3 oz leather, otherwise you will end up with a very thick wallet.
If you are using a F1, you will need a veg-tan Leather since the F1 can not cut through chrome tans.
If you are using a P2 you should be able to select and cut any 2-3 oz leather.
First thing you will have to do is stitch the shortest row of stitch holes on the pockets to your inside sections. Make sure to do both sides.
Now using a saddle stitch, just start at one end of the L shaped stitch holes and work your way around.
Do this to both sides.
Once you have done both side you are done.
If you want to get real fancy, you can bevel, and burnish your edges.
Enjoy!
