This is my new favorite pattern book, and I love that it's a small size pamphlet, which is easy to keep in my knitting bag all the time. It has designs for sizes 2 (child) all the way up to 5X (adult)!
Patons Back to Basics
The book has patterns for cardigans, pullovers, jackets, and vests in all kinds of basic configurations:
Sleeves (raglan or set-in)
Neckline (crew or V)
Styles (plain, striped, or argyle)
Every pattern is designed for worsted weight yarn. (Patons Wool)
