Hi! I'm knitting a bag for my sister and am running into problems with one of the rows. 170 stitches are on the needle and the row instructions are k1, p1, *k4, p2, [p2tog, k1b, yo, p3] 3 times, p3; rep from * to last 6 sts, k4, p1, k1. end with 170 stitches. my problem is that with the p2tog, k1b, yo, i end up with a 1 stitch increase every time I do it... that comes out to 18 extra stitches! could any one help me out?
