Im attempting a Shell Stitch cardigan for my grand daughter and am having a little trouble understanding the pattern. I'm ok with the actual pattern but I've never shaped a neckline using the instructions provided this is how the pattern reads
SHAPE NECK: bind off 4 sts at neck edge once, 3sts once, 2sts 1 time, 1st 3 times, - 34 sts.
Pattern states TO BIND OFF: at beg of row sl st loosely across specified number of stitches. AT END OF ROW: leave specified number of stitches unworked

Cardigan is separated at lower armholes to work L and R front and back.
Hoping someone can help me out with this
