I'm interested in learning some Japanese silk dying techniques but I haven't been able to find much information on them. I was wondering if you might know anything about them? The Yuuzen styles are of particular interest to me. Thank you very much for any help you may be able to supply

No, sorry, I don't know much about them, personally. I have no experience with Yuzen resist dyeing.

For information on Japanese dyeing techniques, I strongly recommend books by Yoshiko Iwamoto Wada, specifically these two:
Memory on Cloth: Shibori Now
Shibori: The Inventive Art of Japanese Shaped Resist Dyeing Tradition Techniques Innovation

A less expensive book on the subject of Shibori is by Karren K. Brito:
Shibori: Creating Color and Texture on Silk

Unfortunately, none of these books has much to say about Yuzen.
