A flag patch is a piece of fabric displaying the national flag of a country. The image of the flag is usually produced by embroidery, using different color threads. Many countries have national patches made to resemble their flags for use in their militaries, although it is not uncommon for them to also be used for personnel in civil jobs, for example police officers, civilian pilots, bus drivers, etc. Most national sport teams around the world include the flag patch on their jerseys of their country that they represent. Some countries, for example United States, have different versions of their flag patch made in different color schemes in order to better blend in with their military camouflage. The three most common alternative color schemes are urban, desert, and woodland. Flag patches can be sewn onto bags or cloth for personalization or decoration. There is a fashion among backpackers to by flag patches in the places where they go and keep them as souvenirs or to show their origin.
