Here's what became of the plastic beads from the aforementioned necklace. I made the rings by threading the beads on large sized plastic coated paper clips, then curling and twisting the clips. I tried some with smaller paper clips, and they did accept smaller beads, but the wire insides are flimsy, and I threw away a lot of my first tries. Too, I needed the larger clips to fit my sausage shaped fingers.
I made about 6 rings so far with lots of beads left, and that's from a dollar store necklace and paper clips, under $3. So another purchase well worth it.
