Posted this over on the 'closing pool' forum, but thought I might get a response here. We have an above ground with deck surrounding on all sides. Decided you can't securely cinch the cover off by the usual 'wrapping it under the rim' method. We've decided to lay the cover flat over the top and extended it out over the deck, then tying off the cover to the posts on the deck. Has anyone tried this approach? What type of rope/? did you find successful yet will still fit through the grommets? Thanks.
