I've been wanting to try this for so, so long. And here are the results of attempt number 1.
I melted crayon bits in the microwave for this project, then poured. The splashing is an annoyance because I wanted clean lines. I intended to make "rainbow pops" but poured too much in the beginning because I couldn't see what I was doing.
So they are kinda funky.
But they color GREAT! I'm gonna try again as soon as I feel like peeling wrappers off of 100 crayons.
