a lot of this was new to me...
Respect for the Flag
"No disrespect should be shown to the flag of the United States of America; the flag should not be dipped to any person or thing. Regimental colors, State flags, and organization or institutional flags are to be dipped as a mark of honor.
The flag should never be displayed with the union down, except as a signal of dire distress in instances of extreme danger to life or property.
The flag should never touch anything beneath it, such as the ground, the floor, water, or merchandise.
The flag should never be carried flat or horizontally, but always aloft and free.
The flag should never be used as wearing apparel, bedding, or drapery.
The flag should never be fastened, displayed, used, or stored in such a manner as to permit it to be easily torn, soiled, or damaged in any way.
The flag should never be used as a covering for a ceiling.
The flag should never have placed upon it, nor on any part of it, nor attached to it any mark, insignia, letter, word, figure, design, picture, or drawing of any nature.
The flag should never be used as a receptacle for receiving, holding, carrying, or delivering anything.
The flag should never be used for advertising purposes in any manner whatsoever.
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.
The flag, when it is in such condition that it is no longer a fitting emblem for display, should be destroyed in a dignified way, preferably by burning."
