However, have you priced those roll up shades for patios? The cheap ones ($22) are plastic and come in 8 ft lengths. I need 40 feet so, five of them will do it, but they won't fit to look nice on the patio. To look nice, I need some custom lengths and those are expensive, plus the plastic will last about the same amount of time a tie wrap does wrapped around a pipe in the sun; 6 months or so. That will get me through the summer, but I'll have to replace them next year. If I get a nice polypropylene shade cloth roll up they cost about $100 each in a ten foot length and if I custom order it to fit properly, the price skyrockets.
