What we used:
* Faber-Castell Paint
* Crayola Crayons
* Cheese Grater
* Cardboard (cut from a pizza box from lunch)
First Monster painted the cardboard.
He then waited a little bit for it to dry.
Then he used a cheese grater over his painting and grated crayon shred over his picture.
While he was doing this I preheated the oven to 200 degrees. Once he was ready for them to go in I put them in the oven for 2 minutes. I could of done it longer but it turned out just fine for the look he wanted.
He did two and they turned out great! I am going to be setting up an art wall for him when we get back from our two week trip to Houston. I want a place to hang all his awesome art that he is doing!
