Suggestions on making homemade outside patio shade cover

If you find the structure I can supply the shade cloth. I manufacture greenhouses and sometimes supply shade cloth to my greenhouse customers. It is a 50% shade that is 12' wide and knitted so it won't unravel. I plan on taking a 35' length to Q this fall and just throwing it over the MH with a couple of ropes, it weighs about 10 pounds. It works on greenhouses why not RV's? PM if you are interested. My cost plus shipping. no profit motive here
