When hung in a window, place the blue union in the upper left, as viewed from the street.
When the flag is displayed in a manner other than by being flown from a staff, it should be displayed flat, whether indoors or out. When displayed either horizontally or vertically against a wall, the union should be uppermost and to the flag's own right, that is, to the observer's left. When displayed in a window it should be displayed in the same way, that is with the union or blue field to the left of the observer in the street. When festoons, rosettes or draping are desired, bunting of blue, white and red should be used, but never the flag.
