The first two necklaces are similar and both consist of a piece of an Alaskan caribou antler which has been brushed with a sealer, wrapped in wire and then attached to an imitation suede thong, which has a toggle closure.
The third necklace was exciting for me to make and I am calling it the "butterfly, birch, bead and bone" necklace. All I knew was that I wanted to have mismatched natural elements mixed with things like beads and metal.
The bone piece is an Alaskan muskrat jawbone and the circle of birch is real. I also strung a few beads together, glued a butterfly in place, and attached a beautiful floral toggle closure (thanks Molly!).
