I'm not a master leather tooler yet (give me another 20 years. lol!) but I am pretty experienced. I feel confident that if I find the right thickness it will do what I want it to. I plan on cutting holes in it (openwork lacy type designs) and probably incising patterns into the surface with a knife, more than doing the traditional western style deep embossing, etc - though if I could find something that was thin enough and could take a stamp, that would be amazing. I would like it to have a little firmness like most veg tan does, because the really drapey garment type stuff won't work well in this instance.
Thanks for the recommendation for Springfield Leather Co. I'll definitely check it out! The pig sounds like it might do the trick!
