Azuma Dyeing is a dyeing process from the Edo period using the kamaire method, whereby fabrics are placed into a small dyeing vat with limestone and plant lye. The end result is a soft fabric with a beautiful texture. The once lost technique was revived by Tokyo's Kawai Dying Works.
Because a smaller-than-typical vat is used, the fabrics must be re-rolled to accommodate the size.
The fabric and dye are placed in the small vat and dyed slowly for four hours. The fabric is stirred and kneaded to create a soft and unique texture.
The fabric is then dried in a dryer or under the sun. Fabrics made this way have a unique wrinkle, and relaxed, soft texture. During the Edo period, soft fabrics such as these were the norm, accompanying the daily lives of the Japanese.
