Could you tell which way the material was stretching? I've heard that the problem with stretchy 1.1 oz. nylon hammocks is shoulder squeeze, but I'm not sure if that's caused by longitudinal or transverse stretching (or the usual suspect - stretch on the bias). I tried to solve a bias stretch problem with a loose weave kevlar fabric (for a stove table, not a hammock) by sandwiching two layers at 45° to each other. It sort of worked ... somewhat.
