Please Help with Solar Cover attachment

[Poconos]

Welcome to the forum. I have a similar geometry with rounded ends and don't worry about the little bit at the end with a rectangular cover. If I really want to conserve heat I do have separate end pieces cut from old covers I just lay in.

Thanks. That's the only idea i could think of as well. I just wanted to make sure there were no other options but it sounds like that is a practical one.
