Chiri-men Craft Museum, Arashiyama, Kyoto.
From the Kyoto University of Foreign Studies:
Chirimen is a traditional weaving technique that was developed in the late 16th century in Japan. The cloth or silk fabric that is made from this technique is also called "chirimen." The cloth has the unique feature of soft wrinkles. According to the pamphlet from the Chirimen Craft Museum, "the wrinkles are created by alternating two types of silk thread, twisted in different directions, by turns in the weft. The woven cloth is at first flat, but the wrinkles suddenly emerge after rinsing dirt out of the thread. This is the moment when the breathtaking beauty of the wrinkles is born."
These wrinkles are called "shibo" in Japanese. The shibo also appear because the weft (the thread being woven) is 10 times thicker than the warp (the set of lengthwise threads). Chirimen is mostly used for finely made kimono. However, in chirimen craft, small pieces of the chirimen cloth are sewn together to create small, artful objects such as flowers, birds, animals, dolls, and small toys.
