Then work in the main pattern as follows: 1 edge stitch, 10 stitches before the pattern repeat, repeat the pattern 4 (5) times, 11 stitches after the repeat, 1 edge stitch.
At a height of 65 cm (about 25½ in), bind off the center 23 stitches for the neckline and on both sides bind off 3 stitches twice in every 2nd row.
