Neckerchief

A neckerchief is an item of uniform worn on the neck in similar fashion to a necktie[?]. In unfolded form, it consists of a piece of cloth in the shape of a right triangle, with the hypotenuse about three feet long. When a neckerchief is to be worn, the hypotenuse side is rolled in the direction of the right angle until most of the neckerchief is consumed in the roll, leaving only a small triangle free. It is then placed on the wearer's back so that the roll is under (or on top of) the collar and the free triangle hangs down. The rolled ends then pass around the neck until they meet in front of it, where they are secured together with a rubber band[?] or other fastener and allowed to hang.

One organization that makes the neckerchief part of its uniform is the Scouting movement.
