I'm typing this on my laptop while laying in my first DIY hammock, and in fact my first sewing project of any kind. I picked up some 1.9 ripstop at Joann's last week, and last night, with some help from my wife, I got the body made. Today I whipped the ends, added the shock cord to the sides a la Knotty, and hung it from the eye bolts in my office/man cave. I like the way it lays- very comfy for me, though I haven't slept in it yet- will tonight though.
Some observations regarding size: I made this one the somewhat standard 10' 6" long, by approx 58" wide. My first hammock, the one I sleep in a couple nights a week, is made from a queen size sheet. It measures 7' 6" long, and about 7' wide. I really don't feel much difference between the 2 other than the sheet fabric is nicer on the skin. They're both super comfortable to me, I guess the extra width makes up for the shorter length. By contrast, my GTUL is just too small for me (6', 190) to sleep in comfortably, though it makes a super lounging hammock.
Anyway, the DIY bug's got me- next up is a stuff sack with the cutoffs, then a bug net, and who knows what after that?
Thanks go out to all who've posted their ideas and wisdom here.
