I used the plastic canvas, too. Just cut it to size and put one of those plastic report binder spines on each edge. Some people glue it to the glass, but I got mine to fit snug enough side to side and top to bottom under the lip of the tank that it didn't move. They can't see each other very well through the canvas, but because of the holes, the water can circulate and I only used one filter.
