This is the pattern Redheart Tween Layer Top WR1736
It would not let me post the link:(
It says:
Shape Shoulder
Bind off at each shoulder edge 3 (4, 5, 6, 7) sts twice.
Does this mean I co by k2tog 7 times, So that I co all the stitches or am I suppose to have stitches left? Is this the end of the back piece & I start the front as a new piece. I don't want to be guessing I want to make sure I understand for future patterns that may be worded this way

Thanks
