I normally scrape the hide fairly clean, stretch it out on a board and use
lots (and lots) of Borax (you can pick it up in the laundry isle- Borax is
what most taxidermists use on their bird mounts to keep pests off.). It
produces a hard hide, but for fly tying it doesn't matter much- except for
zonker strips, I just buy them.


Hope it helps.

My bother-in-law has taken up bow hunting. This is producing some
delicious venison as well as leftover deer skins. How should they be
treated for use tying? Thanks.
