Anotations

Scope note:

Small rugs usually intended for use on tables or chests, typically not on the floor. They comprise circular patches, often of gradated sizes, cut from felt or discarded clothing; the circles were placed one on top of the other, with the smallest on top, to form a button-like form. The "buttons" were then sewn down to a strong foundation fabric. The rug may be embellished with embroidery. Button rugs were popular in the United States in the 18th and 19th centuries.
