I took the Top Down Sweaters class at Yarndogs and produced a knit to fit sweater for my daughter's Amercian Girl doll Marisol. All you needed were 2 measurements, a few calculations based on your gauge swatch (or whatever the ball band says) and you're good to go! As you can see it fits perfectly!
I've got to start something new. Maybe a Top Down Sweater for me -- I'm bringing a picture to our South Bay Knitters guild meeting to show the teacher (a member of the guild).
