Why spend your money on expensive crafts when you can make lovely art with items already in your home?!
Your children will have a blast dipping paint in various objects to see what design each makes!
Here are two examples of household things you can use:
1. Save the end of a stalk of celery--when dipped in paint, the stamp makes a ROSE impression.
2. Save toilet paper tubes--they can easily turn into a HEART stamp! If need be, tape the heart tube in place while in use :)
