Does anyone have any advice on making these? I am about to do a patch job on my garage floor and I think I will have some topping concrete left over so I thought I would use it for this. I have seen some done with pieces of glass or ceramic tile but I would appreciate any tips from anyone who can help. Thanks

You can buy patio molds at home and garden stores. My friend just made plain round patio stones and had her kids put their hand prints in them and wrote the date in the cement. It came out great and she has them in her garden.

Thank you, Clarebear. You have given me all kinds of ideas that had not occured to me.
