I saw a post describing this somewhere - somebody else deserves the credit- but I took it a step further. Using 8mm "mountain climbing" rope (whatever its called), about 3 feet, tie a double overhand knot in each end. Whip the hammock to the space between the knots. The first pix just shows the concept, I did not want to cut this expensive rope just to take a picture, or unwrap the hammock. The green webbing in the second pix is the line to the tree. The black cord in the second pix is the ridgeline.
Tie a strong cord for the ridgeline to set the sag. A lot of discussion about the HH clone and the folding technique and the shape of the fabric. Could the secret of the comfort be the fixed sag enabling asym sleeping??? (As I said before, I'm too cheap to go out and buy a new HH, so I've never sat in one.)
