What do you do with the old skin that snake shed ?

I have boxes full of the things. I keep ones that are not ripped. I am thinking that some day I will figure out something ingenious to do with them that someone will pay for, but it hasn't happened yet.

I keep most of the nice ones. I am going to give a few to a friend who does wildlife education - she already has one or two for props, but different sizes and species are nice.

I usually eat them with a side of salsa.
