Since this is a winging it pattern, I can do what I wanted. Since I like to follow some direction when I wing it, I am following the path of the estimable Yarn Harlot, and knitting for length till I am sick of it. (Yarn Harlot mentions this in her sock knitting instructions in Knitting Rules) That is what I did.
I'm also getting to dangerous territory. Because I am winging it, I'm going to have to remember what I did on the first neckline so I can match the second neckline.
So....I'm going to have to get the other neck side done today. I don't think this is wildly optimistic, but I could be wrong. Still I do have the alternating rows of colours that will help keep me on track and should make this matchy matchy thing easier.
