i've done a few. take the brains from the deer. srape the flesh side real good. then soak the hide in water and ashes . the ashes will make the hair slip. wait til the hair slids off easily. scrape both sides again..then in warm water ,mix in the brains. agitate the hide then let it soak overnight. now comes the hard part. ring out the hide, and start streching it . over a beam, or wrapped around a tree. you can stand on one end and pull the other..you need to keep streaching until it is totally dry. you can smoke it over a punky fire. wrap the hide around the smodering fire like a tipi.. there are lots of books on this . several different ways to do it. this process works for me..it is written that this how the native americans did it...
