Over-Dyed Sashiko Thread (Thick) 40m

Indigo dyed the slow way.

This thread is dyed by hand using fermented indigo — a process that produces colour with a quality that synthetic dyes cannot replicate. The slight unevenness left by the dye bath is intentional; when stitched, it creates a gentle depth and dimensionality that flat colour never could.

Fermented indigo is a living dye, and the thread retains something of that nature. A brown lye may be present in fresh skeins — a natural byproduct of the fermentation process, not a flaw. A simple overnight soak in warm water before first use is all it takes to settle the thread and prepare it for stitching.

The colours shift between lots. Green indigo, yellow indigo, dark indigo, purple indigo, dull indigo — each name points toward a tone rather than fixing one precisely. That variability is the nature of the dye, and part of what makes each skein its own.

Made in Japan.
