You may have noticed Paint rocks and sticks on my family's summer bucket list a few days ago. The photo here inspired the sticks portion. I saw this recently as a submission to threadless.com by ginetteginette and thought it was a perfect summer day activity.
Could be done indoors on a rainy day or outdoors on a breezy warm one. Either way, you'll have some beautiful artwork your kids will be proud to have on display!
