We have a round house and our patio and balcony both are in desperate need of some type of awning. These might be perfect! The fact that the edges curve is a real advantage for us, I just need to determine if they will fit the curve of our house. Is it possible to determine the arc of the curve. If you drew a line from corner to corner and then measured the distance from that line to the edge of the sunshade in the middle of that line I could determine how it would fit on our house. Thanks, Gary
