I'm KLHinNC, and I am a Hammockolic.
I've had this problem for about a year now, and am just now coming to grips and embracing my addiction.
Hammock is a Grand Trunk camo UL from here.
Using a bug net that drapes over the top here. I may sew one side to the hammock and use snaps or magnets to secure the open side.
Suspension is 6' per side of 1" Polypro webbing, using lightweight brass rings, and some kevlar speargun cord (light, low stretch, high strength).
Tarp is a $10 PU 6'x8' camo tarp that barely covers the hammock on the diagonal, so I am looking at the Oldman Winter. Expensive, but better than anything I can make from Sil on my own right now. Also taking care of my NC peeps.
Ridgeline is 30' of the kevlar cord, siberian hitch knot on one side, trucker's hitch other side, using prusiks and paracord for the tarp attachment. I'm a climber, and I love knots.
Finally to the DIY project, an UQ.
I have an old Ledge 20* rectangular sleeping bag. I plan to cut this up to fit me as a 2/3 or 3/4 UQ. It's a synthetic bag, weighs bout 4lbs, but I bet I can cut it down to size and have it under 1.5lbs. Heavy by down standards, but essentially free. Expect it to be comfortable down to the 30*s with a thin CCF pad as backup for in the 20*s.
Will use my 0* synthetic bag that weights ~3lbs.
I have followed the various writeups, and feel pretty good about the parts and pieces. Here is what I have to put it together.
.125" shock cord for suspension.
1.5" Polypro webbing as sleeves for the shock cord sewn to all 4 sides.
A borrowed sewing machine with a #18 needle. (Yes, I am learning to sew for this project)
Please chime in with thoughts and suggestions.
