Newbie needs idea for hammock straps.
Hey thanks for everyone's help! Bubbas method using the slipped sheet knot was easiest as I didn't have to get more items. I went ahead a hacked the hooks off my tie down straps and replaced them with carabiners I had laying around. Little more secure than those hooks as someone above mentioned I figure I could still use them as ratcheting straps in my truck with the carabiners. They're also not that expensive.
As for nylon/stretching. I have no idea. It does feel like nylon but I use them to tie down very heavy machines in trailers. After a year or so of use they show no signs of stretch or fraying so I guess it's a good enough material to hang with. My bosses family owns a rope business. If I were to go to their warehouse for rope to use as suspension, what kind of rope is ideal for long term use?
