Sarasa derives from the same word as 'calico' and was the Japanese response to imported Indian cottons which were first imported perhaps as early as the 15th century by Portuguese traders. During the Edo era, this luxury cloth continued to be imported by the Dutch. Imported sarasa was very, very expensive, despite being a cotton cloth, and reserved for the samurai class. In more recent years, sarasa style has been popular for kimono fabrics, on silk and wool. It usually has beautifully subdued colours.
Olympus Thread Mfg. Co. produced a range of fabrics inspired by sarasa a few years ago, and I've managed to get hold of the very last few bolts! So what I have listed here is absolutely all I can get hold of - unless they introduce a new range inspired by the same style.
