This book contains basic directions for tams, other hats, gloves, mittens, socks, and scarves. I made my first hat from the "Basic Mohair Tam" pattern in this book, and it was gorgeous. There's also a design for a ski-mask sort of item, and patterns for them are hard to find!
Designers can overlay their ideas for color or texture on these simple shapes very easily. This book was written to inspire, not to overwhelm.
I think this book belongs in the library (or knitting bag) of every knitter who wants to knit any of these items. If you only knit sweaters or afghans, this book is not for you.
