So, a few days after washing my sail on the lawn, I see this somewhat familiar shape...


I began to wonder, was the salt killing the grass? But that didn't explain the pattern so much, or that there wasn't THAT much salt...
It looked more like when you leave something covering grass for too long. But it wasn't there nearly long enough, and anyway, it wouldn't die there, where thereWASNT shade...
So I finally came to my last idea... Did I cook the grass though the clear of my sail???
Has anyone else had this?
