>>11586648x8 is the point a quilt is functional as a sleeping bag/hammock(doubled), 10-12 square is when you can build an encompassing tent, by pulling the midpoint of 1 side to the corner of either opposing side, and tying it off above ground to a pole, staking down all the corners
i dont often purvey the use of a hammock out of my quilts, but i do at least once test their ability to do it, as well as how to tie off in a way that preserves the integrity, which ultimately comes down to distributing tension onto the rope, and off the quilt
