Silk worms are raised in the remote villages of eastern Guizhou. It took me 3 years to find members of the older generation who still retained the knowledge to grow silk worms and weave the fabric. The worms are raised between April and June when fresh mulberry leaves can be fed to the worms. Because of the time-consuming process (they can only weave 10 cm of fabric at 40 cm wide), it is very rare to find these fabrics still being made today.
Silk threads are soaked in soybean juice to stiffen it and make it easier to thread into the hand loom. Labels keep track of which village women spun which thread, as the quality can very by person. Generally, the more patient and pleasant a person is, the better quality their silk thread seems to be.
