You will need : foam sheets, pipe stem cleaners, pom-poms, glue, scissors,wiggly eyes, and a hole puncher.
Cut the foam sheet into a strip. Fold it back and forth in equal sections accordion style. Punch holes through the foam sheet, my hole punch did two pieces at a time.
Have the kids thread the pipe stem cleaner through the holes. Fold pipe stem cleaner on each end to keep the foam pieces folded. Cut off ends as needed.
