We found the easiest way to remove the wrappers was so cut through it with a knife first.
Adam made tin foil bowls to melt the crayons it. We just put one color in each bowl and melted them in the oven.
Pour the melted crayon into the mold and let sit. We put ours in the freezer for a few minutes.
And there you have it. We have Oscar, Big Bird, Grover, Cookie Monster, Bert and Ernie. They turned our really well. Thanks to my Husband for doing most the work!
