Abstract: A sign sash is placed around a corner of an existing political campaign or other sign and conveys an additional message. A strip of paper is scored down the middle and folded over to form front and back sign sash portions. The front and back portions are connected at their edges and at least one bears a display. A sign corner can be inserted between the front and back portions and the sign sash allowed to rest on the sign and display the graphic across the surface of the sign. The sign sash is made of rigid card-stock and adhesive and/or fasteners connect the front and back portions. A fastener can secure the sheet to the sign corner or another object. The sign sash is useful for varying sign messages and for adding to the message as events change, for instance to thank supporters after a vote is concluded.
