Hi theresa in tucson,
You are not alone in your assessment of this book. I think she made a sensible decision, I can't imagine how much bigger her book would have been with a coat draft. And, the pants are quite adaptable but still a bit dated. Imagine how much more dated the coat would have been.
The pants draft and assembly instructions could be a bit more concise and clearer, but they work and the draft shows a unique approach to the seat angle that is well worth showing.
