Don't think I've posted this before; I know I haven't put pictures of it up here before. Anyway, it's great. Can swim for hours without burning. It's made of the solar screening fabric and secured by bungie cords to a canopy frame made by stringing rope between 4 metal poles. (We hope to eventually get an entirely metal frame put together eventually.) The solar fabric is extremely light and the bungie cords make it so it goes up or down in only a few minutes. It doesn't matter if it gets wet, so I can do part of the putting up / taking down while actually in the pool. The canopy is actually 2 sections joined in the middle with canopy ties because we were afraid that one big canopy would become a huge kite in even a fairly light wind. This I will keep up in light to fairly moderate winds, but will take it down if the forecast is for a heavy blow. So the fact it's light and easy to put up / take down is important. And it feels so nice to swim under the thing!
