I don't know it just seems that there is a difference in the lay of the hammock. As far as I can tell the whippings are the same and I can't imagine any other reason for the 2 lines of stitching on each side of the hammock unless it was to form some type of taper. Maybe it ends up as a square, but I wonder if there is something else at work.
I have not disassembled my ENO; probably should. Maybe I'll undo the whippings and lay the fabric flat to see if the stitching is straight or curved. Be an easy way to know. I started to do that once, but after attempting to untie the knot for about 15 minutes I got fed up and moved on to something else. Has anyone already done this....Hooch?
