I use ashes from our sweat lodge fire pit, about 4 gallons of ashes. And tide laundry soap. I put ashes and soap in a trash can with water. Mix it up, then put hide in. I mix it every day. About 5 or 6 days. Take it out on a warm day,pull hair off by hand. Then I tack the hide up on a piece of ply wood in the sun. After it dries I make drums with it. I cut it with a jig saw. Nice trick that a friend told me about.
