A balloon arch is a decorative structure made from inflated balloons arranged in an arch shape. These arches are commonly used for celebrations, events, and parties, adding a festive touch to entrances or photo backdrops. They can be customized in various colors and sizes to match the theme of the occasion. Creating a balloon arch typically involves using a frame or support system to hold the balloons in place. The balloons can be tied together or attached to the frame with string or clips. Event planners often use balloon arches to enhance the visual appeal of weddings, birthdays, and corporate events.
