Melted crayon hearts: A boy in my class a couple years ago gave these as little Valentines made out of melted crayons. He said, "For Crayon Out Loud, Happy Valentine's Day". could also say, "You COLOR my world!" Use silicone cups to melt them in.
Paint an eye onto the canvas and then glue small pieces of crayon underneath it. Melt the crayons with a hair dryer and you'll get an effect like this!it's different from the normal crayon melting stuff.
