@zoowar yes - it doesn't work, because as soon as you turn around, you lose the blanket. I've also tried 'lining' the #hammock with a blanked or bedspread but that also hinders free movement in the hammock. The best is still warm air from below, maybe supplemented with a thin cover. And wearing warm clothes. :)
