Leather is sold in ounces and 1 ounce is a 64th of an inch. Therefore 10 ounce leather is 10/64 of an inch or 5/32". As for selling your work it has to be very top quality and I have no problem selling all I can make. My work is not cheap but it is unique and will last the shooter or hunter their lifetime and most probably the life of their kids and grandkids. As an example: not everyone wants or can afford a habu or adcock bow but neither of them has a problem selling them.B/Wlvr
