I love rocks and nature stuff that I can create things with. This is a fun craft to do with kids, my niece and I painted some rocks with various images. Simple and relaxing while watching a movie on a rainy afternoon. You can use these for paperweights, put magnets on the back, if small enough, for the frig, or just decorative in an office. We used acrylic paint, to coat the top you can use any sealer you like, from modge podge to varnish spray.
