"The Crochet Answer Book" by Edie Eckman
Being a "good" crocheter is not just about making perfectly stitched, elaborate, artful creations. It is also a matter of confidence. You need to be confident in what you are doing and in how to figure out what to do if things aren't going quite right.
This book answers some of the most common questions crocheters have, and anticipates some questions you didn't know you had. The Crochet Answer Book will help you gain the confidence that makes for good crocheting.
