Status report: one full 24 round repeat of the cable and lace pattern knitted. And so far, so good.
No dropped stitches. No split yarn. No pulls. No glaring errors in my cable and lace pattern.
I've watched the internet videos on SSK - slip-slip-knit - and produced a series of tidy decrease rows. And I've had good success at keeping my purl stitches tight ... particularly if I whisper "purl at the tips of the needles" to myself under my breath as I go.
I don't want to say too much ... but fingers crossed, these socks might just work out alright.
