A sample book is a way to gather and display a number of pieces of fabric, wallpaper, etc. so that customers can closely examine the product and choose what to buy. It is a convenient way to professionally showcase particular product line options that may be available in various colors, textures, patterns, or finishes. A sample book is typically bound or fastened at one edge. People often browse through sample books when choosing upholstery fabrics and trims, window treatments, carpeting, and wallpaper. The client is actually able to touch and feel the product via the sample book. This helps people make a more informed buying decision.
