Patchwork-use Chirimen Fabric PM-023 This is a Japanese traditional cloth "KYO-CHIRIMEN" patchwork usage measures approx 13.20" X 9.20" . It is a famous material which is known as kimono fabric. The four sides of the fabric are just cut out by scissors, so we would like to recommend you to stitch all edges if you use the fabric without sewing. The CHIRIMEN is made of 100% rayon yarn and it's UN-WASHABLE.. It will be washed the color out and it will shrink in the wash. Please bear in mind that it is not strange. Japanese people usually NEVER wash kimono since old days because it would shrink in the wash. Great for handicraft kanzashi and/or creating your original patchwork items. Recommended!!
