Aargh, have just reread pattern I’m working from and recounted stitches, and realised I’m 10 down. Somehow I’d been reading down a row on the totals, so at the end of round three, I have 156 (I thought I was adrift by 2) instead of 166 
Think I might go and have a lie down. My head is thumping.
We’re not having a learning day, we’re having a fighting day - for some reason today Big doesn’t want to read. I could do without this.
