Can't locate a photo in my archives, but will try to describe another option. One end of sash is gathered into a rosette which is invisibly held with a small rubber band or the like and finished off with a decorative brooch in the center. The rosette is placed on the front of one shoulder with the long end of sash trailing over the shoulder and hanging down behind. The weight of the brooch is enough to keep this in place during light activity (walking, but not dancing). Not having it pinned on allows you to a) not have pinholes in your evening dress and b) easily remove/place it when desired.
