I picked them 12'X12' canopy off Amazon a couple weeks back thinking it would work great to provide some shade when we are sitting at the patio table. How's it holding up? I don't plan to keep it up at all times, will only put it up when we are outside. This picture it is jerry rigged just to get it hanging to see how big it was and to give me an idea of how to mount it. How do you have it mounted?
