Trend sample books are merchandised according to product category—linings, sheers, drapery, silks, prints, multipurpose, upholstery, and trimmings. This easy to use system has each product category represented by a color designation. The color designations are found on the sample book header and spine to provide easy recognition in a sample book library as well as to provide a way to organize the sample books. For example, all of the SILK books have a gold label; all of the UPHOLSTERY books have a green label, and so on.
