What you want to end up with is a continuous line of stitches from the first ones you cast on to the last ones you cast on.
Cast on 6,
then knit the 10 stitches that are on the left side of the center,
pick up 16 stitches between there and the shoulder,
then knit across the 32 stitches that are on the holder for the back of the neck,
pick up 16 stitches between there and the 10 on the other holder
knit the 10 on the holder
and cast on 6 more.
