This circa-1940 vintage rag rug features an intriguing all-over design of densely spaced black lines against a purple background, alternating direction from vertical to horizontal. The resulting feel of the minimalist midcentury vintage carpet is evocative of optical illusions and draws the viewer in for a closer look. Rag rugs are folk craft rugs made from old clothing torn into strips. They can be created by braiding or weaving the strips to form oval, circular or rectangular shapes. The strips may also be tied in knots in 20th century rugs. Rag rugs were originally created out of necessity, with limited supplies and only the simplest tools used to braid and crochet useful floor coverings from scraps of discarded fabric. Because of their authenticity and beauty, vintage American rag rugs are keenly sought after.
