See that? - well, actually, you can't see it very clearly: just refer to the pattern itself and you'll sort of know what my knitting looks like.
I was at roughly this point coupla days ago when I suddenly noticed that I'd done a short-cut in the pattern, half-way back: I'd knitted a purl row and thus started on another of the 4-row pattern with only 2 rows behind it.
Dithered. Fretted. In the end had to acknowledge my indisputable obsessive compulsiveness and de-knit all the way back to remove the offending mis-knit. I'm working on 252 sts, as it's one-piece till the armholes; only the gods know how many rows, let alone sts!, that I frogged. And served me right for losing concentration.
Btw: the thing the knitting's sitting on is my new storage unit. TEN DRAWERS! – I'm in order heaven.
