This is a free pattern on the Lion Brand website. I'm making the large pair...casting on 22 sts. 4 needles w/ 6, 6, 6, & 4sts on 4th needle as stated. Rnd 7 is an inc rnd having a M1 on the 2nd needle ( 7 sts ) and M2 on the 4th needle for the Lg pair ( 6 sts ). That would make 25 sts total...but, on the pattern it says 24 total. Did i do something wrong or is the pattern wrong?
