Any Object!
Almost any found object can be made into a simple elegant pendant or can be used as "beads" for string, in about 15 seconds!
"Ever find something on the beach or on a hike, and say: "Wow, this is neat, I wish I could make a piece of jewelry out of it!" I have many such objects: beach glass, melted plastic or something, and a lot of other small junk things. Now I am going to get them out and turn them into cash, I mean jewelry!."
