This video is about making a mummy type sleeping bag or an over bag for a hammock with a woolen blanket. The first task is to make coat rings and hooks. Take a piece of flexible wire and bend it into a ring of diameter 1 3/4 inch or 2 inches with a overlap of about 1 1/2 inches make 6 or 7 rings. Now take a small straight wire and make a hook of 1 or 1 1/2 inch, make the tips of the wire pointed so that it can penetrate. Overlap the edges of the blanket by 2to3 inches. Fix the rings with the hooks so that both the tips of the hook is penetrated deep into the blanket. In all 6 to 7 rings are fixed to form a tube. This tube can be worn like a pant and pulled up to the neck to act like a sleeping bag. It can be used to enclose a hammock in which you can sleep fixed to the hammock.
