The first braided rugs were created by Early American settlers using old pieces of blankets, clothing, canvas, and other materials. There are several different types of braids. Flat braids are braided around two guide yarns, which makes them more durable. Tubular braids contain a single-core, around which the surface yarns are knitted. Tape braids use three solid pieces of material braided in a traditional fashion. Yarn braids consist of several three-ply yarns which make up one part of the three elements of a braid. Braided rugs are woven with many different materials ranging from nylon to cotton chenille, to wool, and even blends of different materials. The quality is again determined by the tightness of the braid and the materials used.
