I may be the only one who does not like this yarn as the other reviews seem to be good. I heard this was a great sock yarn and ordered a skein to give it a try. I have worked with some wonderful sock yarn in the past, but this was not one of them. The yarn felt harsh and hard in my hands. I literally hated the way it felt to knit with. I don't know if it softens after washing, but that would only mean that there is a LOT of sizing in the unwashed yarn. If it doesn't soften, then I would never want to feel it on my foot. I threw it away.
I bought Jade and the color is deep and rich. Absolutely gorgeous. Make sure to buy the yardage you need all at once, because there are no dye lots and the colors can vary from skein to skein. A true laceweight; it knits up like a dream. I'm using size 6's for a very open lacey effect on this project. I made a 6x6 swatch and stretched the heck out of it and it held up just fine. It has held its block perfectly as well. I might put a touch of starch in it to give it a bit of crispness when it is done. All in all, highly recommended.
