View source for Hat cord

A '''hatcord''' or '''hat cord''' is a circular [[cord (textile)|cord]] around a [[hat]] at the junction of the crown and the [[brim (hat)|brim]]. It originally served to stabilize and hold the hat on the head and to prevent the hat material separating. A '''hat band''' fulfils a similar function. Hatcords sometimes come in imaginative fashion-oriented designs.

In the [[Middle Ages]], the hat cord was also used as a unit of measurement to control the thickness of [[Plumbing|water pipes]]. In order to save water, the water pipe was not allowed to be thicker than a hatcord. According to Duden, it is questionable that the German saying: ''Das geht (mir) über die Hutschnur'' ("That exceeds the hatcord [as far as I'm concerned]") meant ''das übersteigt das Maß des Erlaubten'' ("that exceed the permitted amount")''.<ref>[https://www.duden.de/rechtschreibung/Hutschnur Duden], Abschnitt Wendungen und Redensarten</ref>
