(NEW PRICE FROM 7/21/2008) unit size: approx. 0.8-1 oz. skein weight: weaving suggested epi for weaving: 40-100 (or more) suggested needle size for knitting: N/A (may be #00000000? I think it is a bit crazy, but you can try.) Yes... This is reeeally thin, but strong! Beautiful as warp or weft yarn. Dyes wonderfully, too. (but please be cautious when you unwind the dyed skein. It is tangled. You must have an appropriate swift and also a winder.) If you are not dyeing the skein, please request to have it wound on a cone. It will save you HOURS & DAYS of your time. ($10 per skein winding charge applies) "Organzine" means generally a balanced twist (ply).
