Thick white paper (water color paper, textured scrapbook paper etc).
Step 1: Cut an egg shape from your white paper.
Step 2: Use the white crayon and draw several patterns on your eggs. Chevron, swirls, polk-a-dot, scallops.
Don’t be surprised if you have a sensory kid that decides painting this way is better. (Why not add a little tactile input into this project right?!?)
