Hello, I am looking for the best machine to sew really thick leather. I have always sewn by hand and haven't had much luck sewing though thick leather with my singer 17-16 machine. the needle always breaks or the stitches come out uneven. Is there any recommended machines? I have heard walking foot machines are good. any ideas?? (I make mostly, bags, cases, wallets, belts etc...) Thanks!!
