In a remote corner of Japan, there are a group of people who work together under the name BUAISOU who are completely dedicated to indigo. BUAISOU is comprised of a farm, dye studio, and design-studio and located in Tokushima prefecture, the historical center of indigo farming and processing in Japan. Every year they grow and harvest their own indigo, dry the leaves, and compost them. They combine this compost with wood ash lye, wheat bran, and water and use fermentation to create indigo vats. Within these vats, they dye every shade of blue, on items such as this sashiko thread.
There are two options of thread thickness in each color:
- THIN (20/4)
- THICK (20/6)
When working with fabric, thread, and fiber dyed with indigo, it is common and natural for the blue dye to rub off on one’s hands while sewing. This is called crocking. Although the goods have been washed, it takes pressured contact to release the extra indigo dye. Your handwork is part of the indigo dyeing process. The blue dye can be removed with hot water and soap. From working closely with indigo dyed materials through the making process, typically, the excess dye has been removed, and the crocking will cease.
Please note the fiber content of the material you are working with, and follow the applicable instructions:
Cotton or linen - Machine washable on cool cycle with pH neutral soap. Lay flat to dry.
Superwash Wool - Machine washable on cool cycle with pH neutral soap, though hand wash recommended. Lay flat to dry.
Wool and Wool blends - Handwash only in lukewarm water with pH neutral soap. Lay flat to dry.
