I made a DIY UQ out of a cheap target rectangle sleeping bag.
I did channels down all 4 sides out of 2" grossgrain, and ran 1/8" shockcord down the 2 long sides.
I then took 1/16" shock cord, and used it in the short sides to be able to cinch everything tight.
The finished product doesn't look half bad
The problem is, it's not sitting snug up to my back/butt when I'm in the hammock, there's a good 2" gap in the center.
I've been messing with it for 2 hours, and still can't eliminate it, any suggestions?
