Looking for a simple DIY for a ridgeline organizer. Although I cant see this as being an overly complex project, I have tried a simple tent organizer a couple times, and I've found it tends to slide around the ridgeline a lot. I suspect this is due to the hammock not being 100% level. Aside from taking a level with me every time I go camping, is there an easy/effective way to prevent this problem? I was thinking pursik knots on either end of the organizer, but if there's a better way, please advise.
