My own worst enemy.
No knitting for a week: Before this started I had gotten the Brioche socks down to the beginning of the heel, and either because it was late afternoon or that I was getting sick, I read and re-read the instruction for starting the heel. They made no sense to me, (not because there is anything wrong with the pattern) just because my head was not working properly.
And here is the progress, now to work down the gusset. And, of course, I fretted the whole time that I had gotten so old that I would never understand a pattern again. Glad that is settled.
