I am knitting my first garment for a child, I have managed to construct the cardigan using King Cole Island and Beaches pattern however I am now struggling with my front right border.
As I am working on the larger size as the pattern states to pick up 122 sts which I have done. However the next part of the pattern has confused me as I am not sure whether I should have left over stitches unworked in ribbing?
Next row: Rib 36, cast off 2 sts, [rib 13] cast off 2 sts  times, rib 3
Next row: Rib 4, cast on 2 sts, [rib 14] cast on 2 sts,  times, rib to end.
Work 3 rows in rib 2x2
Cast off in rib
The problem is, I am left with additional stitches still on my left needle as I begin with 122 sts, as this is my first time I am confused as how I should proceed.
Lastly, as I was working on the front right border I feel as though I am creating buttonholes? although the instructions for the front left border explicitly mentions to omit buttonholes for the left side?
Any help to decipher this pattern would be greatly appreciated!
Thank you for responding
