Haven't done this yet, but here's my idea. With the shock cord of the UQ kind of pressing into your face, it's more comfortable if something holds that shock cord away from the hammock. I was thinking about sewing a little tab onto the underside of the "left wing" of the Blackbird and onto the channel of the under quilt, then attaching them with either a piece of shock cord or line with a cord lock. You could adjust how much the under quilt is pulled away from the hammock, if at all, and with a minute of fine tuning, make it so there isn't a gap for cool air to seep in, but the pressure of the shock cord isn't on your face. Oh great HF community, what does your almighty wisdom say about this idea?
