Well, get the shed out of the tank as soon as you can.. preferably when it's still moist. I unroll (if necessary) the moist skin and drape it over something so that only either end is touching something (not the middle, as the skin tends to stick to whatever it dries on) leave it over night, and carefully remove it from whatever it's draped on.

I save most of my sheds.. I have boa sheds wrapped around my bed and my curtain rods, kingsnake sheds hanging off bookshelves.. etc etc.
