To curl up, hedgehogs have a ton of muscle stuck tight to their skin in a big "ring" along where the quills meet the soft hair. I'm in no way a professional taxidermist, but I pelted the hedgehog easily and tried to get to work removing that muscle. Keyword being tried. I couldn't tack the pelt to a board since the hedgehog's rounded skin won't stay perfectly flat. There was also an added worry of a hard board and harsh scraping snapping the rigid quills. A dull knife couldn't get under the muscle to force it off the skin, but a sharp knife just cut the muscle into strings. I currently have the pelt under a lot of salt to dry it out a bit and see if that helps, but otherwise, I'm at a loss. Any ideas?
