How does this work? Pattern help needed!

I am making a sweater fr my son’s doll. I am following a knitted sweater pattern for a bear out of ‘Knitted Toys’ by Fiona McTague. The pattern is simple until the neck shaping… the pattern is as follows…

Shape neck
next row
k15 turn
work on this set of stitches only. Dec 1 st at neck edge on every row until 10 st remain
work even until front matches back at shoulder shaping ending at armhole edge,

Now, Im not a great knitter, but I am good at plugging along and this has me stumped. The picture shoes a slightly scoop neck, and then you pick up stitches along the neck edge to make a turtleneck of sorts. But those instructions dont work for me. I dont understand! Help!?
