Wife is still missing the knife, and i think at this point has just forgotten about it. There will be 3 phases, or intially only 3, phase 1 6x1 back piece(done), phase 2 6x3 to cover the front part of pond, and phase 3 12x3 to cover side of pond. Since the pond is next to a wall i dont need to cover that side or the back of it. I might be covering the top part of the pond to make it all flow together. I told the wife i would have it done by Sept my sons birthday, and at this rate i hope to get it done by then. I try to work on it for 30 min a day.
