Wanna a super cheap (free) painting experience for your kiddos? Collect some rocks, make your own paint (HERE is a super, easy recipe using sugar, corn starch, water and food coloring), and there you go!
We read the story Stone Soup, made some stone soup using veggie broth, celery, carrots, potatoes and corn. Then we painted with stones to round out our theme. The kids really "rocked" it!
