Step 1: Read a caterpillar book...gotta love this one!
Step 2: Cut an egg carton in half lengthwise. We then cut that in half too, so that our caterpillar could move his "hips" a bit!
Step 3: Poke two small holes in sides of caterpillar's head. Thread a long twist tie (pipe cleaner would work too) through holes and curl up ends.
Step 4: If your caterpillar has two segments (like ours) poke one hole in each and attach with another twist tie. Leave about 1 1/2 inches of space between body segments so he has some "wiggle room".
