Hey John,,,,
When you're skinning a squirrel, if you're very careful, you can actually pull the entire tail bone out of the tail leaving just the whole tail and skin. It takes a little practice but after awhile it's very easy. Lay it flat in warm dry place and it'll cure on it's own.
As for the hides, you can buy tanning kits but what I've done a few time is carefully scrape all the meat and fat off the hide, stretch it on a board nice and tight and lay a coat of kosher salt on it to help it cure. Just leave it alone,,, the salt will soak up any of the moisture in the hide and cure it. After it's good n cured scrape the salt off and you're ready to hang it wherever you want......
