Even though I am a beginning mosaic artist, I want detailed information about design techniques, materials to use, and errors that are common to the craft. This book fills the bill - it's got first rate design information and provides examples of the discussion topics. The arrangement of the topics in alphabetical order may be something that others find less than desirable, but if you read the entire book before making any judgments, you'll find that this is a non-issue. I'd recommend purchasing this book, especially if you only want to buy one.
