I read this some 20 yrs ago,a cheap soluion to keep people warm. Thought of sharing over the net so that the idea may be used by some body to help the poor.
Essentially you put two piece of news paper sandwitched between two sheets of pvc. This can then be stitched or pasted to make airtight joints.
Price of the items is almost nothigs but this thing is very warm; better than many costly woolen garments. Mind you, it is not recommended for continious use. One may wear it over another clothing.
