Balloon arches are decorative structures made from inflated balloons arranged in an arch shape. They are commonly used for events such as parties, weddings, and grand openings to create a festive atmosphere. The arches can be customized in various colors and sizes to match the theme of the event. These arches can be freestanding or attached to a wall or other support. They are often created using a framework of PVC pipes or metal to hold the balloons in place. Balloon arches are popular because they are visually striking and can enhance the overall decor of any celebration.
