Austrian knot
From Academic Kids
An Austrian Knot (or Tyrolean Knot) is an elaborate design of twisted cord or lace worn as part of a dress uniform, usually on the lower sleeve. It is usually a distinction worn by officers; the major exception is the hussars, in which Austrian knots are worn by all ranks. British Cadet Under Officers wear Austrian Knots as part of their rank insignia.
During the American Civil War, Confederate officers often wore gold Austrian Knots on their uniforms. More elaborate braiding indicated higher rank.
