I've thought about starting a "what can we make out of yogurt cups?" thread here and perhaps now I don't need to, because that's such a cool idea, heathersy! I like the idea of the plastic paint, but I also like the perhaps-lower-impact idea of decoupage. Of course, the plastic painted version could go outside on trees and gutters, etc. Hmmmmm. At this time I don't have any yogurt cups, because I am able to recycle them locally, but not at the super-handy curbside like most of the other recyclables. I'm bookmarking! I can't wait to see what you come up with!
