Often an afterthought when it comes to home decorating, floors, curtains, and lighting are essential to creating a complete, finished look in any room. These books are "very well organized," explains Cynthia Conigliaro. "They have great illustrations, and they're organized by style." If you know you want hard tile floors, you can skip right to that section of the book. On the other hand, if you're clueless about which type of floor will perfectly accent your living room, leaf through the book to figure out which combination of colors, textures, and finishes is appropriate. Each book includes a "Practicalities" section that explains how to assess your needs and shows you how to do renovations yourself. There is also a directory of suppliers.
