This was a fun and easy painting project. I found this idea on Charlotte's Fancy and she has step-by-step instructions. I thought they would be perfect rainbows for St. Patrick's day decor.
I love these Bingo style dot paints, they are easy even for toddlers and so mess free. You can get real bingo dobbers, but watch out, they are not washable and may be slightly toxic.
We got ours at Fred Meyer but they have them all over.
