I always love a book that gives me more than one way to do things, and Lily Chin's Knit and Crochet with Beads doesn't dissappoint.
It is out of print now, but if you find a copy of it, snatch it up!
Seven methods of knitting with beads and seven more using crochet are followed by an extra section on looping, bangles and spangles.
Projects are interspersed throughout the book and range from sweaters to clutch bags. They all seem approachable and well-explained.
If you haven't explored adding beads to your work, this is definitely the book to get you on your way. Experienced knitters will probably find new-to-them techniques, as well (I know I did).
