We made our own many years ago and they are still going strong. We bought Coolaroo fabric online for a few hundred dollars and sewed it to make hems and a sleeve on the bottom in which we put a piece of conduit to weight it down and around which it will roll up. Some cords and pulleys provide the motive power. Installed on inside of the screen. Marine twist tabs help hold it to the wall at the sides in a breeze.
