I know the typical shade sail shape is bowed on the edges because of tension, etc. but is it possible to get a completely square shade sail? And also to have that shade sail be completely sealed/flushed on two edges against a structure?
There are already places to attach the shade sail/fabric solution.
From the picture below, I would like it flush/sealed against side A and B, and then angled down from A to C. All corners have a place to attach the sail/fabric.
Is there any solution that I can implement in this area?
