Rock Tumbling For Autism
I haven't met a child who is not fascinated with rocks at some stage of their life. There is no experience equal to seeing the excitement on children's faces when they talk about collecting rocks. I hope to inspire my readers to delve into a kind of art that requires no physical talent, but only imagination, a little bit of patience, and the rock tumbler of their choice. Many thanks to David Leaton.
