More new patterns and weaves were introduced in the last ten years than in the previous half century. 1 A nation-wide study made by the United States Department of Agriculture in 1957 showed that "approximately 76% of all homes had soft floor covering in the living room." Forty-nine percent of these were room-size rugs, 14 percent were wall-to-wall carpeting, and the remainder was composed of scatter rugs
