Step 1: Go outside and hunt for a good rock. (We have found that large, flat, round rocks work best.)
Step 2: Set up a painting station (inside or outside). Protect the ground or your table with a cloth or old paper grocery bag. Get out your brushes and your paints and put some water in a dish so you can wash your brushes between colors.
Step 3: Paint away! You could make your rock rainbow colored, or you could give it a face or even cheetah spots or turn it into an insect! Note: If you want to go “all natural” try creating colours from nature – mud is good for brown, berries make purple, and a crushed up dandelion soaked in boiling water makes yellow!
