You know my blue eggs? I saved the shells, hoping I can use them in some way. I had envisioned collage, and I boiled the washed shells hoping to peel off the inside "skin" when cooled. Well, I started, but the shells kept braking into smaller pieces as I peeled the skin, so I've stopped. The skin is much tougher than commercial eggs, and adheres to the shell with gusto. (Which makes sense when you think about the primary raison d'tre of eggs and their shells!)
I can take the skin off, crush the shells, and maybe mix the powder with paint??? Or is there a way to get the skin off easily and still keep the shells in reasonably-sized pieces?
