Satin cord, also named rattail® cord is a shiny smooth cord made of rayon with a cotton center made in the U.S.A. It is often used for cords of necklaces, stringing beads with large holes and knotted pieces. Recently it is also used for kumihimo and ornamental Chinese knotting.
Personal Note :: I have been using satin cord almost exclusively as the central core of hand braided kumi cords for many years. Since the satin cord is hidden inside the braid, I mostly use either a dark and a light color. I like that it is slippery, so it can be removed easily if the core is temporary. In addition the satin cord have no elasticity, so the braids will not stretch over time. I prefer the official 'rattail' brand over other satin cords made with nylon. It drapes better.
