12' X 20'  Rectangle Shade Sail is really handy in the summer days. The problem I have is that I have not been able to get anyone to put it up for me. I used to be able to do anything when I was younger..ANYTHING! But now I am 66 years old this month of November 2021. I deal with chronic pain and some other problems and it really restricts me.  I would recommend it for shade. I think it would work great.
