I'm repairing the horse for a Santa themed bar crawl in a few weeks. I modified the rear legs to pick them up a little more from the ground, so hopefully they'll last this time. Cale made a support for the tail so it won't bounce up and down when I ride. I'll have to get some updated photos up soon.
I used duct tape for a little extra strength. The rear legs flex up and down a bit, so if there's something in there that can't rip, it should hopefully be able to stand up to a few hours of riding.
Followed by lots more paper mache, of course.
