A winter hammock blanket. The one unique thing about it is the 1.8 Airwave on the bottom that keeps it from sliding off a bed or sofa. In fact, my wife has already stolen it for use on the sofa.
I followed the blanket making video on the website here. My only adjustment was because the blanket was too big and heavy to slide around a sewing table easily, I just flopped the material on the floor and slid my sewing machine around the perimeter to make the main stitches.
Required Materials:
Airwave 1.8 on the bottom, .66 Membrane 10 on the top. Apex Climashield 10 oz for filling. KAM Snap 20s on perimeter. A chonky 4 lbs total, but this and a plain hammock is all I need for cold, clear winter nights.
