I was in China last month and I believe that one of the most useful items I ever bought was a silk quilt.
When I was a child I remember my auntie rearing silk worms and making her own silk.
For those who know very little about these things let me sum it up. The tiny powder like silk worm eggs hatch and they feed on mulberry leaves. It is a joy to watch them grow daily. The Worms grow to a length of a few centimeters and then they begin to spun their homes so to speak. They make their cocoons and seal themselves inside. After a short time the silk worm inside the cocoon become a butterfly, pierce the cocoon and get out. I think it lays eggs and dies.
The cocoon is thrown into hot water and then they start pulling the odd end of silver thread. It is one continuous piece of thread about 1200 metres long. This is how they obtain silk thread and wove silk cloths. However sometimes two worms start spanning the same cocoon and both of them end up in it. This is double cocoon and it is impossible to obtain silk thread from it because it is impossible to separate the two silk threads from each other. hence it is of no use for obtaining silk thread from a double cocoon.
Double cocoon is used to make silk quilts. They throw it into hot water and then stretch it over a small glass pyramid. Then they stretch the same cocoon over a bigger pyramid. Then four people hold the cocoon, one at each end and pull it until it stretches to the side of a king size bed. They put layers and layers on top of each other and then put it into a linen over, then into a silk cover. Very light and very soft. I think it is possible to use single cocoons too. No stitches or anything to hold it in place, it simply stays stretched. So now you can make your own. I am sure cocoons are available from villages
