I had to frog the whole thing! Well, I was only on row 27 but it still hurt. I dropped a stitch in one of the open laddery spots and it was just too obvious. I fiddled around for an hour trying to make it work but in the end I couldn't live with it so I ripped it out. This time I will be more careful.

I think I'm going to do a lifeline so this doesn't happen again. This is my first project of this type. How many rows should I do before I move the lifeline? 5, 10, 20? I don't want to be too obsessive.
