The Flag Code, which formalizes and unifies the traditional ways in which we give respect to the flag, also contains specific instructions on how the flag is not to be used. They are:
The flag should never be dipped to any person or thing. It is flown upside down only as a distress signal.
The flag should not be used as a drapery, or for covering a speakers desk, draping a platform, or for any decoration in general. Bunting of blue, white and red stripes is available for these purposes. The blue stripe of the bunting should be on the top.
The flag should never be used for any advertising purpose. It should not be embroidered, printed or otherwise impressed on such articles as cushions, handkerchiefs, napkins, boxes, or anything intended to be discarded after temporary use.
Advertising signs should not be attached to the staff or halyard
The flag should not be used as part of a costume or athletic uniform, except that a flag patch may be used on the uniform of military personnel, fireman, policeman and members of patriotic organizations.
The flag should never have placed on it, or attached to it, any mark, insignia, letter, word, number, figure, or drawing of any kind.
The flag should never be used as a receptacle for receiving, holding, carrying, or delivering anything.
When the flag is lowered, no part of it should touch the ground or any other object; it should be received by waiting hands and arms. To store the flag it should be folded neatly and ceremoniously.
The flag should be cleaned and mended when necessary.
When a flag is so worn it is no longer fit to serve as a symbol of our country, it should be destroyed by burning in a dignified manner.

(j) No part of the flag should ever be used as a costume or athletic uniform. However, a flag patch may be affixed to
the uniform of military personnel, firemen, policemen, and members of patriotic organizations. The flag represents a
living country and is itself considered a living thing.
Therefore, the lapel flag pin being a replica, should be worn on the left lapel near the heart.
