A friend gave me a great idea of how to use all the broken crayons that breed in our house. She melted them into little patties and they are great for coloring or making rubbings.Here is how we did it. First collect all the broken bits and peel off the paper.
Then fill a muffin try about 1/2 full with crayon bits and stick it in a 250 degree oven for 15 minutes.
Take out and cool, preferably outside. Once the patties are totally cool they pop right out and are ready to use.
