Toba Garrett’s book The Well-Decorated Cake is great if your are interested in learning more elegant cake decorating skills. The book includes many recipes, and is full of color photos. Toba’s directions are clear and well written. The chapters include some construction techniques, but focus mainly on design using just about every decorating technique you can think of (and just about any kind of frosting you can think of).
I’ve been so pleased with Rose’s recipes that I haven’t tried any of Toba’s, so I can’t recommend it for the recipes, but if you are interested in more elegant cake design techniques and ideas, this book might be for you. I checked a copy of it out of the library before I decided to purchase my own.
