When considering options to create shade on our deck, I didn't want a permanent structure as it would be in front of our dining room window and we would lose a lot of sunlight through that window in the winter if we could not remove the shade cover from the deck. We decided to build a square frame that we could attach and remove this sail from. It works so beautifully and we have done it for three summers now. It's lightweight which makes it easy to do this every year and easy to store. I am so thrilled with our decision and love the quality of this product.
