With a bugnet installed you don't need to add this mod. This is is intended to create a faux footbox that keeps the TQ in the hammock. I've done this to my gathered end hammock and it hasn't affected the lay of it for me, but it has kept me from having to chase my SB over the side of the hammock. Before the mod, I would wake up several time through the night to wrestle the foot end of my SB back into the hammock.
