One of the most important tool is the standard latex balloon. Used for balloon arches, bouquets, and drops, standard latex balloons are round balloons that come in a variety of colours and diameters. They often have messages printed on their surface for special occasions. Most often made by filling standard latex balloons with helium, balloon arches are a very common prop used by event party planners. Balloons are often attached to a wire framework and anchored at either end by weights. By mixing colours and shapes, balloon arches can be quite dynamic.
