We ordered this in able to provide some shade over our patio. We live in southern California and it has been consistently over 100 degrees this summer. We have a wooden pergola of 2x4s thinking that it would provide a good base for stability of the sunshade. It does. The shade fabric is a woven nylon and a deep brown color. Our issue with this is that it came with no instructions or mounting hardware. Each corner does have a metal d ring. There wasnt even a picture in the packaging for reference.  Question if this was a return We mounted it with deck screws on all edges.  We really dont have wind issues so we will see how it holds up.  I would recommend this if it included hardware and instructions.
