Yeah, I'm gonna rip it out and try it again. Wish I'd seen the errata sooner. I know better too :S
ETA I wrote that one down, it's not quite the same. I can't even find Barbara Walker's version charted. This one goes
K2, yo, ssk, yo, k3 *sl1 k2tog psso, yo, k1, yo, sl1 k2tog psso, k3, yo, k1, yo, sl1 k2tog psso, yo, k2tog, yo, k1, yo, k3* and then the end 13 sts. Has 8 beg sts, 20 pattern repeat, 13 end sts.
*goes back to ripping out and trying it again*
