We recently installed this Yardistry gazebo. (Pic from the internet not my actual space!) I need a shade on the side that is 14 feet if mounted on the inside, or 16 feet if mounted on the outside. I have been told that it’s better to get 2 separate smaller blinds. I am just wondering how to get them to stay stationary and not flop around in the wind? Our patio is brand new concrete that we installed last summer. Does anybody have any ideas? (Curtains are NOT an option). I live in Canada if anyone has any products we can use to solve the problem.
