your pattern does an increase. Right. one more increase than decrease per repeat. That may just be right.
one repeat 10 (original) stitches, right?
k3 * yo (yarn over) K2 SKP (slip stitch, knit stitch, pass slip stitch over)K2tog K2, YO, K1.YO K1
repeat from * to end. K1
that is for original stitches:
yo (yarn over) K2 SKP
(slip stitch, knit stitch, pass slip stitch over)K2tog K2
, YO, K1
so 4 pairs plus 2 = 10 stitches.
plus 3 initial and 1 final stitch...
that makes 5 repeats of 10 = 50 + 4 edge parts = 54... so what on earth is this repeat good for if it does not cover all stitches? Or does your pattern say something about 2 edge stitches to be worked or anything?
when finishing the repeat there are 11 stitches, as you found out.
So when you work that as instructed, it should come out to be 63 stitches at the end of the row.
Is there a link to the pattern? That may help.
