A quick consult with the original (and awesome) Leila and I was able to bind off the right front properly. So then I went to cast on the left front. And the phone rang. It was an old pal, who needed to reschedule a get-together, and we got to talking, but I decided I could multitask.
Bad idea.
I got all the way up to the armhole shaping, and realized I was TEN STITCHES SHORT. I went to 28L instead of 38L. Sigh.
Note: The electric yarn ball winder is an excellent frogging tool. Ribbit.
