item #: NS-18J 21/10x2 silk organzine degummed content: 100% silk yardage: approx. 1400 yds. (1260 mts.)/skein regular price: $24.00/oz. (sold from 1/2 oz.) weight: lace/weaving suggested epi for weaving: 30-40 suggested needle size for knitting: US No. 1-2 Dyed by an indigo dyer in Japan without any synthetic chemical in the vat. The color will do the job for you! If you are a dyer yourself, there is a white available also. Please take a look at NS-18J. Great weight for those weavers, who are beginning to work with finer yarn. *** The naturally dyed indigo yarns need to "age." The darker color indigo especially will "dye" your hands at first as you work with it. This is because indigo never penetrates "into" the fiber, but simply sits on the surface of the yarn. After letting it sit for several months and also washing repeatedly, the color will settle. The blue will simply get better from there on.
