So the directions said to drape it over the coping but it would not stretch, admittedly it isn’t warm enough but to see nice hot temps in Minnesota will take a while, we took the coping off but left the stabilizing rails on and then the instructions say once 24” high water to put the rails all the way back together with the liner under it all. We got it to work but it was such a pain, I’m really hoping we don’t wreck the liner this year... or maybe I do because it’s not pretty. Haha
