i have been tooling leather for about 6 months now and have taken a few pieces to a local trade day/swap meet type event and i am starting to get people wanting my work. so i have decided to get into leatherwork deeper and start making more stuff to sale. my question is i am having trouble deciding on a good weight for leather i make things such as wallets, guitar straps, and fire helmet fronts. as for wallets and guitar straps what are some good weights of leather for these items? any help is much appreciated!
