Check out The Lord's Prayer Art Workshop, written by Carol Hulbert, from First United Methodist Church, painting Prayer Rocks.
Do you take your church kids camping? At end of above lesson I tell how we did this activity at our girl's Spring Weekend Camping Trip, at our local Provincial Park. Friday evening, we headed to the beach for a scavenger hunt to find our perfect stone, which they then painted the next morning, outside on a picnic table!
