egg cartons kids craftCut out an egg carton strip each for yourself and your child. It’s merrier when you paing together – and you can show the kid what to do by painting your own caterpillar. The carton is sturdy enough so young kids can use as much paint as they want, again and again. After everything is covered in paint, add the legs, the eyes and the mouth with black paint. Use two toothpicks for the tentacles.
