I first read about this project at Crafty Daisies.  Here’s how I do it!  Peel and break up crayons to fill the compartments of a mini-muffin tin.  I have a little one who’s just as in love with peeling and breaking as coloring, which is what sent me in search of this project in the first place.  But if that is not the case with you, and you just have some little fingers that need to learn how to make big strokes without holding a flimsy, frustrating, crayon, then may I suggest an Exacto knife for peeling.  Anyway.  Bake at 275 until the crayons are melted (around 7 minutes) and then put the whole muffin tin in the freezer.  In about 30 minutes, the beautiful crayons will just pop right out!  Ready to use.
