A couple inches into the cuff, it became extremely obvious I was working on coordinating, rather than matching, socks. I knit these at the same time, using the same number of stitches, and yarn from the same dye lot. It occurred to me, I may have wound the yarn from opposite ends of the hank. Hmm.... shouldn't the color repeats be the same length regardless and appear, well, in opposite order if that were the case???
They start to match up almost identically after the gusset, despite no difference in increase/decrease rates between the two.
