Cloth napkins are a staple for most full-service restaurants. While disposable napkins are always an alternative, cloth napkins are more supple and pleasant for your customers to use. When choosing a cloth napkin, the most important consideration is the design of your dining room and table top. Choose a color that will match your dinnerware as well as the color of your walls, ceilings, art work and other décor in your dining room. It is also important to choose a napkin that is large enough to fit all the utensils. Commercial cloth napkins vary in size from about 17 inches to 20 inches wide. Most are square in shape, so you can fold them into whatever shape you want.
