Making stepping stones has been on my to-do list for a long time now. You and your family have given me the inspiration to make it a top priority. I'll need to make lots of them as they will be defining a path from a cottage on our property to our screen house, a distance of about 30 feet. I really like what y'all did with the glass shards. I do have a question. What is the reason for curing the stones under water?
