A lecturer, writer, adviser on decorating and owner of an antique shop (in Woodbury, Conn.) supplies an everybody's-purse book on antiques and decorating which has a basic soundness and logical approach. The homemaker will find here a rule of thumb which is a pleasant departure, less perfection in decorating for more comfortable and happy living, and the advice that a professional decorator be used in an advisory capacity rather than given carte blanche. With sections on color, wallpaper, fabrics and furniture, this then takes up the four major architectural and decorating periods -- Early American, Colonial, Federal and Victorian, with the backgrounds of their customs, costumes, interiors, furnishings and accessories, and ends with the creation of today's interiors following the lines of the preceding material. There is an appendix on historic houses (by state), a bibliography, and a list of the manufacturers whose wallpapers are mentioned. Good for reference and safe as both a beginner's and a guide book.
