We had a nice little collection of broken crayons and so we found these cute chocolates silicone moulds at Kmart Australia for around $2 each, the kids enjoyed braking them up even more into tiny pieces and fill up the moulds, we put the oven on around 150degrees, popped the moulds on a tray in case any wax melted over the sides, we kept an eye on these for around 15 minutes or until fully melted wax. Wait until they are fully cooled before removing from moulds. Tadaaaa….. sweet little crayons, perfect for gifts or the kids to proudly use!!!!
