I dip dyed veg tanned leather with Angelus leather dye, and the results are beautiful. I have "sealed" the front with atom wax, and that has actually stopped any ruboff from the front. I am trying to figure out the best seal for the back (flesh side) to prevent dye ruboff. I have atom wax, resolene, and leather sheen at hand. These are going to be for holding restaurant checks, so people will be handling these pieces a lot, but I don't have to worry about constant rubbing, like from a belt.
Any tips on how to seal that flesh side?
