Stamps on rocks are a super-easy way for children to create #wordrocks.
The tip is to choose clear and smooth stones.
Another important thing: the stamp in acrylic paint will smudge. Therefore, I only get a beautiful result when I stamp directly on the original surface of the stone.
Then just use the stamp, wait for it to dry quickly, and use coloring pencils to create beautiful rocks.
After a few hours, seal it with Triple Thick Glaze or Twinkles.
