Hey Jason,,,,
I basically do just what Barry said,,,,, I scrape all the meat and flesh off the hide, stretch it out really well, salt it down - rubbing the salt into the hide, and let it cure. I've found if I do this it works our realy well and the hides retain their shape, display well and there's no unpleasant odor. There are also commercial tanning kits you can buy, but I've never used one. Might be interesting to try one one of these days though.......
