From the 1940 Youth Leadership pamphlet for new members of the Jungmaedel, "The Jungmaedel Service":The neckerchief and leather knot are always worn with your blouse. The neckerchief is a black triangle that is folded until only a small corner of about three fingers shows from underneath the collar in the back. Your leader will teach you how to fold the neckerchief. The leather knot is natural brown in color. It's used to hold the neckerchief.
