Anybody here know about leather work? I want REALLY STIFF leather to use for the front, back, and side of the bag. I want the back leather to fold over the front and become front closure/flap. Really simple bag that I think with some time I can make incredibly nice. Any help on where to get this really stiff leather or even what it is called? Also what to sew it with...obviously by hand because I am probably not buying a sewing machine.
