My fault, really.
I was here:
And then I went to look at the book to find out how the armhole was going to be handled. I'm doing a set-in sleeve from the top down in the round, and the instructions are... well, spread throughout two or three chapters.
But that's no excuse for what I did. Rather than increasing four stitches every other round, I did them EVERY round. So I ripped it out.
That's what, four times now? Five?
I am so sick of this sweater.
