The causes that the American flag represents and the sacrifices that Americans have made for their country and for their flag necessitate a certain degree of respect for the flag. Accordingly, the American Flag Code lists the ways in which the flag should and should not be displayed.
Several aspects of the Flag Code are common sense. The flag should always be displayed right side up, with the union in the left as the viewer sees the flag. Unless the flag is properly illuminated, it should remain on display only during daylight hours. The flag should be raised and lowered in a brisk fashion, and when you lower the flag, do not let it touch the ground.
If you have other flags besides the American flag, the American flag should be either in front, and at the center, of the other flags or on its own right in a straight line with the other flags. Flags of other states (including Texas, contrary to popular legend) can be at the same height as the American flag, but none should be higher than the American flag.
You should not use the American flag as a costume, as an item upon which you write, or as a carrying container. In addition, you should not display the flag in a way that it could be easily torn. In other words, flag napkins and the post office’s stamp of the American flag are, to some degree at least, a violation of proper flag etiquette. While it is acceptable to wear clothing that displays a picture of the flag, you should not have writing on the flag itself or utilize it for advertising purposes. Of course, the important issue is simply that you properly and prominently display an actual flag; remember what the flag represents and respect it, however it appears.
