Summarize this article:

The flag should be folded in accordance to national tradition. It should not be crumpled or folded in such a way that results in creases or wrinkles. Store the flag in a spot where it will not come into contact with anything that can soil it. Some flags have different folding techniques for certain occasions. The US flag for example requires a triangle fold when used at a burial. When a flag is no longer in good condition, such as if it is torn, ripped, or badly soiled, it should no longer be raised or displayed. It should be disposed of in a dignified way as required by the nation in particular. If the flag is currently being flown, it should be removed and folded in standard respectful fashion.  The standard disposal technique for flag disposal in the US is a respectful burning.  Some organizations, such as the American Legion, will take old, worn flags and dispose of them appropriately. A flag should not be used to create apparel, bedding or drapery. Flags must be allowed to fall free, and not be drawn or sewn in ways that restrict this. The flag should not be used as a covering for the ceiling. This includes using the flag as a makeshift bag or purse! Most are familiar with not allowing flags to touch the ground. However, a flag should not teach anything that is beneath it. This includes the floor, water, parts of a balcony, or even merchandise. Desecration of a flag is punishable in some nations. In the US, desecrating the flag can lead to a fine or no more than one year imprisonment. Some nations requires individuals who carry a flag to not “dip” it, or turn it from an upright position to a horizontal position. This indicates deference to those present. Some nations practice this for national events, such as the Olympics, and others do not. The flag cannot be made a part of any sort of advertising, such as being embroidered on pillows or napkins. Staffs that are flying the flag may not also fly advertisements for a product or company. It should go without saying that a flag may not be altered to feature text or other imagery.

Summary:
Fold and store the flag appropriately. Dispose of a worn flag appropriately. Do not use a national flag as a textile. Do not allow the flag to touch anything beneath it. Do not dip the flag. Do not use the flag for advertising.
