When the piece measures 34-35-36-37-38 cm bind off for armhole at each side every other row: 3 sts 1 time, 2 sts 0-1-2-3-4 times and 1 st 2-3-4-5-6 times = 82 sts remain for all sizes. When the piece measures 52-54-56-58-60 cm bind off the center 20 sts for the neck. On the next row dec 1 st at each neck edge = 30 sts remain on each shoulder. Bind off when the piece measures 54-56-58-60-62 cm.
I thought I would give you the full instructions so you could read them. Does this make a difference in what you said to do? One row even in between 3sts BO and 1st BO?
