laser disc - I know it isn't a great picture. This is a laser disc. I crocheted two pieces the same and then around the edges of both, encasing the disc. My husband put a tiny hole near the top edge, to put a small cord or ribbon through. I have the cord long enough for the disc to twist and turn, the light reflects off the disc spaces that show through the crochet, flashing nice colors. The laser disc has the reflective surface on both sides, when I use smaller cd disks I put two of them with the label surfaces together, leaving the reflective surfaces on the outside.
