I havent tried a longer hammock yet. I guess I could run out to wally world and see if they have any cheap fabric left and try to make a longer one. Its worth a shot.
My friend has an ENO hammock and its the only commercial one I've ever seen in person. I havent had a chance to try it out though so I have no idea how it feels.
I was wrong about the whipping I'm using. I'm using the whipping from this thread: Asymmetrical Experiment
I think I'll go home and try headchanges design before I buy more material.
