"Painting rocks is fun for all ages! All you need is some rocks, acrylic paint, a sealer and your imagination.
For supplies, we have had great results with acrylic paint from the dollar store. We suggest either Outdoor Mod Podge (the green jar) or a spray like Krylon Low Odor Clear Finish or Rust-Oleum Crystal Clear Enamel. If there's room on the bottom of the rock, consider tagging it with #haysbororocks.
You can see some of the other amazing rocks at https://www.instagram.com/haysbororocks/, and the tagging will help others find them. Feel free to post rocks you find on your own IG with the hashtag #haysbororocks so your neighbours can find them, or email your photos to firstname.lastname@example.org.
Please leave the painted rocks in the playground for everyone to enjoy. But feel free to take home a rock to paint and bring it back to share!"
