I have made oodles of these stepping stones with my daughter. A quick fun and easy mosaic craft to do with kids or alone. We used glass pieces which you can find at dollar stores, mosaic tiles and lots of shells we picked up at the beach!
After a lesson on pop art I gave my students several options of iconic, products who's logos haven't changed. They chose one, drew it, and repeated it at least 4 times. I then had them paint them in different color patterns of their choice.
