I have a swing on my back porch and the birds would sit on the bar overhead and make a mess of the cushion. So I took some old CD's and drilled 1/8" holes around the edges. Then I ran yarn through the holes and glued the ends on the back side. I hung it over the swing and I don't have bird poo on my swing anymore, yea! I made one and used it on a scrapbook page for a dad who likes music. You could run yarn through it (add beads) and make a dream catcher (Prayer Catcher) or hang items down from it and make wind chimes. You can paint the CD's and modge podge round photos on them and hang charms from the holes.
