What you will need:
Blank or old scratched CDs
Clear fishing line
Pour some glue into a bowl, and use the paintbrush to paint the glue all over one side of the CD.
Stick the jewels all over the CD in any pattern you like. Allow to dry a bit before turning over and doing the same on the other side.
Cut a piece of the fishing line and put through the hole of the CD. Tie tightly.
Hang up by tying the ends together.
Do not put the CDs too close to each other, as they may get tangled by the wind.
Enjoy looking at them as they shine and spin in your succah!
