From Habu Textiles: “This is a cotton dyed with natural dyes such as persimmon tannin, bengara or a sumi charcoal. Very strong warp yarn. Looks beautiful in simple stockinette, but also great in seed stitch or just garter (very three dimensional) It may feel stiff in the beginning, but will soften greatly. The color lot is not stable, so please purchase enough for a project.”
