Ornamental festoons are decorative swags of fabric, foliage, or flowers that are hung in an arch or looped around a room. They are often used to decorate walls, ceilings, and doorways for special occasions such as weddings, parties, and other celebrations. The term 'swags' is derived from the Old Norse word 'sveggja, ' which means 'to swing.' Swags can be made from a variety of materials, including silk, velvet, and paper, and they can be decorated with ribbons, beads, and other embellishments.
