The knitter's handy book of top-down sweaters by Ann Budd
It is exactly as the title will have you believe. A really useful book that gives clear instructions for knitting 4 basic sweater types in multiple sizes and weights of yarn. After that it's up to you to add whatever touches you choose, and there are plenty of additional tip, techniques and instructions for making your garment your own.
The instructions are clearly laid out, and the book is hardback and ringbound, making it joy to use.
