I've got a full skin of a younger paint mustang horse, 5-6ft long, about to be tanned. I bought it already fleshed and salted from someone. No carcass measurements or anything... Where would you start? I am comfortable with making wrapped exelsior bodies with wire frames for my smaller mammals, and foam carved or cast heads, but is this probably too big to use that method? Thinking I would carve the head from foam and sculpt details onto. I know this would be a very difficult project. Is it impossible to get right? I have been around horses my whole life, and always drawing them, so horse anatomy is something I'm extremely familiar with. But the biggest lifesize I ever mounted was only a coyote, deer fawn and some foxes. Any tips or advice for this project would be greatly appreciated! Its a beautiful pony and I would love to do something awesome with it. Once it is all tanned and stretched, how would I measure it to try and make the form? Thanks so much.
