Norwegian Handknits: Heirloom Designs from Vesterheim Museum by Sue Flanders and Janie Kosel
I love this book. I have been a fan of colorwork for a long time, and this book has a great amount of variety.
The patterns are arranged in order of complexity of technique. Chapter 1: Using Basic Knitting Techniques, Chapter 2: Simple Knitting with Embellishments, Chapter 3: Two-Color Knitting and Chapter 4: Adventurous Techniques. This book is great no matter what your skill level is. Additionally, it will tempt you to try something a litt outside of your comfort zone. Upon flipping through this book, I picked up needles and immediately cast-on two of the projects: Entrelac Wristers and Entrelac Sheep. This was my first entrelac experience, and I found the instructions excellent.
There are patterns for Hats, Socks, Mittens, Knapsacks, Sweaters, Pillows, Stuffed animals, Shawls and more. There are "how-to" technique illustrations attached to the relevant pattern (eliminating to flip and hope that the technique is spelled out in the book). The book has a little bit for everyone, and I would love to have this in my personal library.
