This is a very long post, don't miss the video at the bottom!
eBay seller ryujapan-99 sells kimono and components (obi, kumihimo, fabric, etc). At one point the above lot of obi jime was up for auction and sadly I did not win. I wanted a closer look at that green obijime. I'm thinking that it's not actually kumihimo, but maybe a phoenix tail sinnet. Can you tell from looking? Let me know what you think!
See swathes of kumihimo in their signature showcase as part of samurai armour and armament at the Asian Art Museum in San Francisco, California. Exhibiting through September 20, 2009. (via)
