peel the paper off all the crayons
break them up into pieces that fit the muffin tins
oven at about 150 degrees
melt for 10-15 minutes
let cool
pop out of tins
Don't let them melt too long or the colors will get icky. You just want them to bleed a little bit and be able to see the different colors better.
I like to put all blues in one, greens in another, etc. Because I can't stand random.
