If I remember right (I'm not looking at my hoodie right now, but I think I can explain it...), look at the inside of the hoodie and pickup stitches that are in the same straight line from where you're working now... It's kind of weird when you're first doing this because the left and right fronts end up overlapping to make a V that goes into the hood. So you're kind of picking up sts for the left that have already been done on the right, if that makes sense. There is going to be a row where the same sts suddenly spawn off into two directions on the next row. Or put another way, since you already did the pocket, picture picking up 24 sts from the back to form that second layer, its just that you're not going to reconnect the two layers back together... instead, they're going to split and form the hood.
I hope that makes some sense. i agree that a picture would be helpful... but my digital camera is at home (as is my hoodie, while I'm at work) and I don't know how to upload yet, otherwise I'd oblige... I hope this helps some!
