I got an idea to make a rope hammock out of 550 cord since I like it better than duct tape and I'm familiar with it being former USMC. Made one attempt using simple square knots at the junctions and that was pure failboat. I did some Google searching and found HF, but the first thing I noticed was that I've found virtually nothing relating to rope hammocks. Either my search-fu is awful, or there just isn't anything. The kind of hammock I'm looking to make is like this one from Home Depot. Yes, it's generic, but I'm ok with that.
Is there a reason they're not talked about much? Why are fabric hammocks preferred over rope/cord hammocks?
