I was curious about this because I have some Japanese kimono silk called Oshima Tsumugi. Part of the creation process involves burying or dyeing it in mud. But I'd never heard of a Chinese technique for it. Guess what I found through trusty Google:

The article says mud-silk is produced in Southeast China and parts of Southeast Asia. I am now officiallysince my ancestors came from the former and I was born & bred in the latter.
Full moon appears to be optional.... but sure makes it sound romantic (DS muttered werewolves...)
Thank you so much for this very interesting link to a particular textile history
