High Quality Content by WIKIPEDIA articles! Banners are a significant part of the Culture of Northern Ireland, particularly for the Protestant/unionist community, and one of the region`s most prominent types of folk art. They are typically carried in parades such as those held on the Twelfth of July, Saint Patrick`s Day and other times throughout the year. Generally these are organised by societies such as the Orange Order, the Ancient Order of Hibernians, the Royal Black Institution and the Apprentice Boys of Derry, and the banners are typically commissioned, and represent, a lodge within one of these societies. Banners are also carried by trade unions and church groups, and by marching bands. Most banners are painted by professionals and executed on silk, although canvas was a more popular material in the past. Most have a painting on each side, usually depicting different subjects, and the name and number of the lodge. Most banners have one subject per side, surrounded by flourishes, scrolls, and other decoration. Despite being in many ways a sectarian art form, Catholic and Protestant banners are usually very similar in terms of style and composition. Apart from subject matter, the main difference is colour: Orange Order banners make heavy use of the colour orange and to a lesser extent red, white, blue and purple, while Catholic banners tend to feature a lot of green.
