Ok. My question relates to my bind off stitches. I've included my pattern up to that point for reference. The pattern is as follows:
Establish Yoke Pattern: Row 1 (RS): (K1TBL, p1TBL) 12(13-14-14) times, k7 (7-9-10), *k1TBL, p1TBL, k1TBL, k7(7-6-7), rep from * twice more, k0(0-3-3), (k1TBL, p1TBL) 12(13-14-14) times.
Row 2: (P1, k1) 12(13-14-14) times, p7(7-9-10), *p1, k1, p1,p7(7-6-7), rep from * twice more, p0(0-3-3), (p1, k1) 12(13-14-14) times. Rep these 2 rows until piece measures 12" from beg, end on WS.
Shape Armholes: Bind off 13(15-17-17) at beg of the next 2 rows - 59(59-61-65) sts. Work even in pat as established untl piece measures 13 1/2" from beg, end on WS.
Should I be using the exact stitches as they are called for in Row 1 and 2 when binding off the first 15 stitches or just stitching a simple knit or purl stitch? Also, what does it mean when the pattern says to "work even in pattern as established"?
