A great variety of buttons were used mainly on men's clothing during the 18th and early 19th centuries. Generally thread and fabric covered buttons were most common on civilian clothing and metal buttons were used on military clothing but button molds used for making thread and fabric covered buttons have been found at all military archilogical digs in some cases in great numbers. Some extant garments have metal buttons covered with fabric. The least common of the buttons were horn which were made in small numbers in England and exported. Thread buttons were used on the collars of men's shirts and other undergarments from the late 17th into the early 19th century.
