First a broken needle, then the sock doesn't fit! So I tried on the sock before knitting more today & it wouldn't go over my heel. I'm knitting this yarn at a pretty tight gauge and with the high cotton content there isn't a whole lot of stretch to it, so I had to rip it all out and start over.
I cast on again, going up a needle size and adding a pattern repeat. I managed to complete 9 pattern repeats in length, so I'm very slightly further along than yesterday. And I have 5 knitting days left - better get busy!
