I tell you, I like silk. Love it. I don't know a whole lot about it aside from the fact that it is a dream to work with. But from what little I have read....silk brocade is pretty popular (Silk jaquard is apparently the poor mans version of brocade, and later period....easier to produce, from what I understand)....I have read that changeable silk was also used. I used changeable silk for my red stays. That is about the extent of it from me....but if I run across anything else, I would be more than happy to share.
