Thanks to the both of you for replying!! I haven't yet got all of the books I want, and Knitting Workshop is on the list, as are all of Zimmerman's books, so that wouldn't help quite yet, however, I will definitely check that out.
Ingrid, thank you! You said that and a lightbulb went off, so that must be the way to do it. I still want to do some basic shaping, but I think I've already worked that part out in my head how to do that by just increasing the saddles and where I want the slope of the shoulders. That would also help because the pattern would be worked in one piece from the collar down to the cuff.
Now if I did the basic shaping, would I pick up the stiches along the side one row at a time then? We're just talking the little drop in the front for the neck which I might just have to work a few rows with only a few stiches increasing on each side of the saddle for the neck shaping, then across one full row picking up the neck band, which could possibly be at the end of the saddle shaping - which would drop down about 2 inches on the shoulder to chest area, basic shaping for the slope of the shoulders would be worked with the increases on the saddles, so that I'm not worried about. Does that make sense?? - it works out in my head and it wouldn't be that hard to do. Hmmm...going to have think through this, because it would be so much easier to do and I could have him try it on in stages.
