The main concern I may have with your plan is putting the cardboard on top of the cloth. I really do not know if that will slow decomposition of the cardboard or not. It seems like it may. Someone else with specific experience may be able to chirp in on this. The idea is for the cardboard to decompose in one season. The cardboard does not attract earthworms, but does help in smothering the grass, and then kind of opening up a border for the earthworms to move up into the bed. I am not sure if the openings in that cloth are too small for earthworms to want to crawl up in between the holes or not.
