I am a bonehead. I got to the heel on my sock last night. Rather than do the heel when I was tired, I thought to myself,"Self, tomorrow when you are well rested, put a lifeline in and then do the heel. That way if it is short, as you suspect, it won't be a pain to fix."
Riiiiight. I did the heel, completely forgetting the lifeline idea. Foot too short, heel too pointy. Dammit. I ripped back. Didn't quite get all the stitches the way I was supposed to. Need my tiny crochet hook to fix. Naturally it has gone walkies. I am on my way out to get a new one, thus ensuring the old one will reappear toot sweet.
Ciao-grrrr
