I got some cool silicone trays to make alphabet crayons. After peeling the label off of a TON of crayons, I placed them in the trays (you can order them off Amazon). I decided to do multicolored crayons so I mixed them. I put them in the oven on 270 degrees for about 20 minutes. After letting them completely harden, I popped them out. Fun!
I have other shaped of trays to try- hearts, shells, animals, palm trees, & ducks. I can't wait!
