I'd give it a go if there was money in it. I already have a fleshing knife, two other knives, and some tanning chemicals. Pretty much all I'm missing is a fleshing board, I've been too lazy to make one.
That said, out of all the foxes I've shot or snared there's only been one with a pelt I wanted to keep. Unfortunately for me, and more unfortunate for him, he had a giant hole in him But he was the deepest richest red looking fox I'd ever laid eyes on.
