This an excerpt of a post from my other blog.
a hoarder ecologically conscious like me, you feel bad about throwing away CDs that you don’t need and noone wants — AOL junkmail, old driver software for equipment you don’t use or even have any more, freebies from magazines, that sort of thing. One way I get a lot of extra uses out old CDs is to use them paint palettes.
I paint mostly with craft paints and mix a lot when I’m painting miniatures so a small palette is great to have. You could buy something to use as a palette, or use foil, wax paper, or other disposable things. But I think you should use what you have and avoid creating waste that will go to a landfill.
Step 1. Have a CD you were going to throw away
Step 2. Turn it over and use as a palette. Remove dry paint every few painting sessions by peeling or scraping off dry paint. Once in a while a CD will be so heavily coated with paint and glue that I finally tossed it. But I have found that CDs make good terrain bases too, since they will not warp from exposure to dampness or glue.
My daughter also uses CDs in craft projects. This is one incorporates a quarter of a chestnut shell, a synthetic cork with an animal print on it, and a bunch of glass beads.
