Ok, so I have a disclaimer on the crayon craft I just posted. Don't put the crayons in a metal tin. You must put them in an aluminum tin, then on an aluminum tray. I put the stars on a metal tray, and they spilled. Then I tried to put the tray back in the oven to melt the crayons for easy clean up, and smoked up the kitchen. The stars turned out great, but the kids like them so much that they don't want to use them. Oh, well!
