The Antique Ingrain American Flat Weave Rug is a remarkable example of 19th-century textile production from the Centennial era. Crafted in around 1875, this wool rug features a durable and reversible flatweave construction characteristic of traditional ingrain carpets. The design showcases a complex, tessellated geometric pattern with alternating octagonal and diamond-shaped medallions in an allover composition. Its vibrant palette includes deep reds, warm coral tones, and brown hues that provide a sophisticated backdrop for any room. With a low 0.25-inch pile height and rectangular shape, this room-sized rug offers both historical depth and graphic clarity. It serves as a practical yet decorative furnishing, providing insulation and aesthetic appeal while representing a significant chapter in American weaving history.
