Query: Excellent book to have when learning to brain tan.

When I recieved my copy, I did not know anything about brain tanning hides. With this book, I learned how to tan, and successfully completed 15 of 30 hides this past summer (the other 15 were tanned in a different fasion). I am so confident in my abilties to brain tan with this book and personal assistance from all the folks at braintan.com, that I have already placed orders for 80 hides this season, plus panning to pick up additional hides along the way.There are other books and videos available on the market dealing with this, but my personal recomondation for you is to get "Deerskins into Buckskins" to guide the beginner and refresh the advanced tanner in brain tanning deer skins.
