Easy Crayon hearts! Simply put old broken crayons into a Reynolds fun shape cupcake holder (about 2 layers of crayon), put it on a cookie sheet and slip it into a 250 degree oven for about 10-20 min. Let cool. When about half way cooled poke a whole in the top of the heart and insert hanger. Let finish cooling and then peel away the foil!
You can also use metal cookie cutters, just be sure line your cookie sheet with foil so the crayon doesn't make your sheet yucky!
