I cut a carton in half and removed the middle egg dividers. Each girl got to paint half of the carton with the colors of the rainbow.
After they had dried, I punched a hole in each end with a hole punch and tied a piece of ribbon to each hole. I tied the ribbons in a bow under each girls chin to make a little rainbow hat.
Something about the hats gave M the giggles.
Have you had any simple costume ideas lately?
