I just discovered this alternative shading device on line that I absolutely love. It’s a shade sail that can be attached to trees, posts, or other elevated, stable structures that provides shade in quite a unique and artistic fashion. The fabric is constructed in a geometric pattern and is reinforced so that it pulls tight across an expanse to a tension that allows it to be stationery and if installed properly, will not wrinkle, flap in the wind, or sag.
You can find these inventive shade devices at backyardcity.com. They have other cool outdoor accoutrement worth a peek too!
