I mainly used different variations of a W fold before gathering. Depending on the fabric (mainly elasticity of different materials), the most effective I found was to gather the head end as normal, and make a W fold at the foot end...then on the side AWAY from where your feet go, roll the V (of the W) before gathering the whole thing and whipping.
That took up some extra flappy material and made me pop right into the diagonal. Sometimes, dimensions and elasticity created a calf ridge...other times it made the hammock more comfortable.
Subtle. and very interesting. I had not realized that the W was not not just a folded or pleated end before gathering. Your pic at http://www.tothewoods.net/HomemadeHammock2.html
makes that clear.*
You note that the effect / benefit on pocket and central ridge tunnel AKA "calf-pressure" depends on the fabric. I wonder if that dependency is why the answer to the next question is likely no,
Is this pinning-as-though-tailoring incorporated in any commercial design?
*In my campaign against 20K frames of video, requiring 10 minutes to watch, I'll reiterate that your single "stop-frame" pic also shows the unbalanced and asymmetric trailing-away to one side that you associate above with natural foot pocket formation for one diagonal.
