So here's a necklace I completed after finally getting some jump rings.

(sorry about all that stuff in the background. I'm a meticulous note taker.)

It's made out of a bone which I cut like a loaf of bread to get that thin piece. Since it already had the natural hole, I put in a jump ring and then attached an earing I found one day during my chemistry class. Finally, my sister gave me one of her teeth which I promptly drilled a hole into and attached that to the earing.

Hope you all like it!
