Which one are you stitching?
Sashiko? Kogin? Hitomezashi? Boro?
What all 4 techniques have in common, and how they differ...
....when manufactured cotton cloth became available, the peasant class continued to use indigo to over dye their sashiko stitched garments and bedding. The indigo strengthened the cloth, and no doubt gave coherence to the pieced and patched garments and household linens....
....The wives being often too poor to purchase bundles of rags individually would group together to purchase, clean, sort and sashiko stitch the rags together to make clothing, bedding and household fabrics. It is around this time that white cotton thread appears in sashiko stitching.
