I picked the 20 x 10 foot size to cover our back porch that is about 24 x 11. We wont be able to install for another week or so but I wanted to unpackage it and get a feel of the material and inspect the hanging rings. For its size, I like how the 4 corners look as far as having extra reinforced stitches and sturdy metal rings for hanging. My only concern is that it only had hooks on the 4 corners and nothing on the sides. We shall see how it survives some heavy rains.
