Directions Cut the egg carton into sections. Paint and decorate each section according to whatever critter you are trying to create. Glue on the googly eyes. Punch a hole for the mouth. Depending on how many legs and how long they will be, cut the pipe cleaners accordingly. Punch a hole into the cardboard with a paper clip for each leg and push the pipe cleaner through it, twisting it into place. If your insect has antennae, punch a hole through the top and thread the pipe cleaners through, twisting them into antennae.
