A ganse cord is a type of cord used in millinery to give shape to a hat.
It was used extensively in the 18th and 19th centuries, particularly in tricorns, bicornes and shakos used in military uniforms.
[1] The cord is tied in a special knot called Noeud de franciscain.
[2] The ganse loop made from the cord was also used to hold the cockade in place on the head covering.
