Debbie Bliss Sweater


I have 182 sts on a circular needle. I am supposed to divide stiches on to a straight needle. I have to (right Side) k91 sts turn and work these sts only. Dec one st at beg( neck edge) of next and foll alt row. (89) sts.
Then Beg with a k row con. straight.

My question is
I knit 91 sts and turn which is a P row. Do I Dec there? and the next row?
I do not know how to get to the [size=18]k[/size] row to continue straight.

Thank You :notworthy:
