1. Fly the American flag higher than your other flags. We all like to show our pride for home states, sports teams, colleges and more, but the flag of the United States should always be at the center of any display and should be the highest point of a group.

2. If it's flying horizontally or at an angle, the "union" (the stars) should be at the peak of the flagstaff. The union at the bottom symbolizes "dire distress."

3. If you're suspending it on a rope between buildings or houses, hoist the flag out, union first, from the building.

4. Don't lay the flag across a car in a parade or on a parade float (unless it's hoisted on a flagstaff).

5. Bring your flag inside in inclement weather -- unless you have an all-weather flag.

6. Raise the flag at sunup (or later), and take it down at sunset, unless you have proper lighting to keep it illuminated during the night hours.

7. Don't let the flag touch the ground. It's a sign of disrespect.

8. Don't substitute a flag for a table cloth; using the flag in any manner that might result in it getting dirty is a no. A flag on a small pole in the center of the table is acceptable.

9. Flag pins should be worn on the left lapel, nearest the heart.

10. Flags that are tattered or torn should be replaced -- contact your local veterans organization or Boy or Girl Scouts to find a flag disposal service near you, or send it to the Flag Keepers.
