Came across this today...http://www.treestuff.com/store/catal...item=89#detail
Anyone use this stuff before? It looks pretty neat how you just run it through itself like it the third picture. It seems like it could work to suspend the hammock, just one line, no straps or other cord. Just bring it around the tree and through itself once, then adjust as needed, then continue to run it through a few more times once both ends are where you want them.
Can't tell if the stuff is bulky or not from the picture.
