Oh, petra, I don't mess with bones. I tried once and my house still stinks. My father in law who actually does taxidermy professionally thought it was hilarious that I tried to boil the dried flesh off a muskrat skull (it was vile) cuz they are infamously stinky. I got that bone from ShesSoWeird who sometimes actually buys things from etsy to have them sent directly to me to make something from. She's the one that had the idea of the bangles. Actually, the beadcap the crystal there is in is from a repair necklace she had sent to me. Anyways, do a search for 'animal bones' in the supply section, there's tons of lovely specimens, like so:
Oh, and Debi- it was $200.
