>>419979>do people do it, or is it not worth it?Most of the time, furs are going to be taken from stuff that has fur - ie: Long fibers.
Deer don't usually have that, so they wind up being tanned hide (leather).
As far as I know, they're a similar process, but full tanning requires you to strip the fur from the pelt to get the leather. Just getting the fur, you only process one side (the inside) as far as I know. Even then, you'll probably want to sew in a lining unless you like raw leather rubbing up against you all the time.
Also: Tanning is nasty as fuck. You'll need a stripping agent that is strong enough to clean the leather, but not so strong that it damages the material. It smells horrible usually because it's typically some kind of slow-acting organic compound. Exactly what, I don't know. I guess it's a base.
Different levels of agent yield different kinds of leather - also what you start with has a lot to do with it, but you can make it supple and pliable, or you can make rawhide / hardened leather. Shit's an art and a science at that point. Science in knowing how to get what you want. Art in employing it creatively to suit your needs.
