This is one of my favourite knit books and definitely the one I use the most. There's a great variety of accessories, hats, scarves, socks, gloves etc in many different sizes and includes instructions for the same patterns with different weight yarns. This book is great and such a useful took whether you are a new knitter or one with more experience. The patterns aren't difficult, the instructions are through and easy to understand.
I also have Kate's beyond knit and purl, also a great book and just recently purchased her new custom socks book. You can't go wrong with a knit book of Kate's! ( )
