I need clarification on a Zoe Mellor baby bootie pattern. I've done the cuff and then the pattern reads "Divide for top of foot. K25, turn, p13, turn. On 13 sts, work 4 rows in stockinette " It continues with more instructions for working the 13 sts. I don't get it...I'm starting with 38 sts, so if I knit 25 and then turn my work won't I be purling 13 sts onto the partial row of 25 I just did? I've made socks and have always k2tog when I began to turn the heel....maybe this is something completely different? Any thoughts? Thanks!
