National Cemetery compliant memorial flags, coffin drapes, cotton memorial graveside stick flags, and memorial military and civil flag cases.

National Cemeteries require cotton flags. Flags are placed at gravesites or along the main entrance, referred to as an “avenue of flags”

The National Cemetery Administration does allow graves to be adorned with flags the weekend before Memorial Day and the flags can be removed shortly after the holiday. With this allowance, flags may not be illuminated at night, which is a deviation from the flag code, but it is an authorized deviation, according to the cemetery administration.
Flags placed at graves should be erected in a uniform matter, centered one foot in front of the headstone or grave marker.
Memorial Day is the most important patriotic holiday of the year in a national cemetery. In accordance with 4 USC 6(d), the flag of the United States will be flown at half staff until 12:00 noon and at full staff after 12:00 noon on Memorial Day.
