Here is a cute and simple idea. Be a CRAYON!
Find a sweat suit that matches the color of crayon you want to be. Using black construction paper or even dark colored contact paper, write the word CRAYON sideways down the front of the sweat suit. Make yourself a matching pointed hat out of construction paper. Staple a string to it and tie under your chin if necessary.
