This is my wife's first leather project. We could not find info on how to line it, so she chose to do it with pigskin suede. It is nice material, but the dye comes off on skin when you work with it. Does anyone know how we can treat it so it won't rub off on shirts worn underneath? We are considering spraying it with waterproofer for leather shoes. Thanks in advance. Also, going forward, is there a way to actually treat the pigskin suede before it is applied to the project?
