Did you read the Knitter's Review of noro sock yarn? I appreciate the honest review. I too am frustrated by the plethora of knots that show up in all of noro's yarn. I don't think I've ever had a skein that didn't have a knot in it. Now, I'll be happy to go and take the knot out and spit-slice to avoid having to run in ends.
I appreciate the good review and will use it as I explain to people the benefits and drawbacks of the yarn. The color is great. And it's a thin yarn and needs to be knit on the smallest needles to keep the fabric tight so it doesn't wear out. That means I'll be knitting on a size zero needle. I've got a skein of this stuff divided in half to try to knit. Of course, these fall lower in the knitting queue than I want, but there is knitting to be accomplished, right?
