Nicer than a shade sail over the pool? This is a good summer shade idea. Clip on in the summer, clip off in winter or bad weather. Could run between two permanent shade structures, or between two parts of the house.
These retractable shade panels easily pull back when shade is not desired or when foul weather is threatening. Stainless steel supporting cables are included. Custom sized for an existing trellis or to fit within a new stand alone frame.
