Just thought I'd spread the word. Reconstructing History is going to be donating 25% of the money they bring in through the sales of their historic Japanese patterns to the Red Cross disaster relief for the tsunami and earthquake that hit Japan.
RH has a handful of Heian-era Japanese patterns, they're pretty expensive, but from my past experience with the company, I can say that the also include LOTS of documentation that makes it well worth the price.
Just thought I'd give a heads up in case there's anybody else out there who's been interested in this era and would like their costuming to help others
