Right side of the neck with the cable decreases.
Left side of the neck with cable decreases. Can you see the pattern error???
My solution: avoid the (s)uckers altogether.
I wrangle past neckline issues and begin blocking on corkboard, only to discover it's really wonky. I had been considering marking lines on the corkboard, but was concerned about where the ink would end up, so I bought a fabric cutting board for more accurate blocking:
Wonkage remains.
I frog back to before the neckline split.
I refresh the yarn, having absolutely no idea how to do this, but someone else (?) mentioned on their blog that they did it, so at this point, why not????
