Saving hides for fly tying

[kmacisaac]

So I was fortunate enough to harvest an elk this season and I've just completed the cutting and wrapping. I got to thinking that I would like to save a chunk of the hide for fly tying. I'm not familiar with tanning, and I've looked up everything from salting to borax to get the job done. I was wondering if I could simply stretch the hide and let it air dry in my garden shed. I'm not big into tying but slowly getting the knack and I like the idea of reusing some of my own harvest.
Any suggestions appreciated.
