You or maybe the pattern...must be missing an asterisk! Otherwise the directions can't work out as written. When you get to about the fourth row, there's an odd stitch at the end.
If the directions read:
Row 1: Slip 1, *m 1, k 1, repeat from * to end.
the directions can work out because you'll always wind up with an even number of sts.
Hope this helps.
BTW, I did a kfb (that's knit front and back) on the first row 'cause there's no bar there to pick up!
