This 18'x12' Rectangle Shade Sail is absolutely amazing.  We are building a house on 20 acres and we have no shade.  First of all the fabric is beautiful, the color is just like what Wayfair shows and this Sail will last forever.  The color is striking and after we use it for shade and once we finish building the house, we will use it over our swimming pool.  My husband and I are so excited and we know it is going to last a long time.  Right now it is going to give us much needed shade in this 90 degree summer heat.  Then it will be used with our new swimming pool so we will have some shaded areas in the pool!
