Just wanted to share a Krowtann experience. Tanned a full deer hide with intentions of a rug in front of my recliner. Fleshed the hide, mixed the krowtann following the directions to a T. Let sit for 4-5 days in tan. After following the wash and neutralize instructions on bottle I brushed a heavy coat of "Rittel Supersoft Oil" found in dan rhinehart catalog (catalog # SO-320) onto the hide. I folded skin to skin and put in bottom of fridge to sweat for about a week. When I took it out it was soft to the touch very pliable and great leathery texture. Also, I might add that I krowtanned this skin last year (fall 2007) and froze it. I just recently took it out (fall 2008) and did the oil job. So here we are 3 months after oiling and it is the same as it was when i took it out of the fridge. The only issue I had was around the very outer edges of the hide where I did not flesh very well it is kind of stiff, but not hard as a rock. Am currently trying this method on a cow hide, will let everyone know how it works out.
