I made these suncatchers from old cds.  I super glued two CDs together with the shiny side out.  Got out my drill and made a hole near the edge.  I purchased some fishing swivels and ornament holders so when they hung around the garden (great for keeping deer away) they spin and cast rainbows.  I decorated them with plastic gems.  I used a glass glue to adher the gems.  Using other glues either would not hold them or they melted the plastic and clouded the gems (super glue caused this).  I made some with beads hanging down as well.  I just drilled a hole opposite from top and two more about 1/8  of the circumference on either side.  I used large plastic beads and fishing line.
