The hide from a buck that I shot in the neck on the floor is one that I did with the tanning formula. I fleshed it with my hunting knife....lol. It's about 10 years old and no hair slipping at all. I had it on the back of a couch but my Daughter recently got her own place and we gave her the couch that it was on. I've done coyote, beaver and weasel with it so far and they all turned out good.
