just learn to do it yourself it's super easy
How do you do yours? I've got one from last year that I'm going to do, maybe this weekend, to practice on. My plan was to skin it out and remove as much flesh as possible with a knife, then boil it for 5 or 6 hours (or until the meat's fallen off) in water with some borax mixed in. I'm still undecided as to whether I'll leave it the natural color or hit the skull with some peroxide to whiten it.
Is that about it, or are there extra steps you do?
