I also am looking for this - where can it be purchased? What is the name of it? Most concrete walkway molds I have found online are ones where you have to remove the piece from the mold and then place the piece in place like a brick (at least that is the impression I got). The one I want is the one that you put in place, fill with concrete and then you pull the mold up, match the mold to the next position and continue the process. It comes in a brick pattern and I think like a flagstone (river stone) pattern.
