My 5-year and I had our homeschool session this morning. We tried finger painting on a canvas. Trust me this art does not look as great as it is in the picture. The camera made it look more vivid but we are very happy with the outcome.
Crayola washable paint. You can find this everywhere even at Walgreens.
