think trout - Did you ever follow through on your shade idea? I looked at this idea briefly, but it was too expensive for the area I was considering.
I did find that some of the cloth manufacturers do have specials on leftovers and "seconds" that were much cheaper. I think the seconds were instances where the cloth got a few folds going onto the roller. Not good enough for a country club pool, but great for a pond.
Good luck on your trout.
