Banners can have various finishes, such as hemmed edges, grommets, pole pockets, or reinforced corners. Hemmed edges provide a clean, professional look and prevent fraying. Grommets are metal eyelets that allow for easy hanging using ropes, bungee cords, or zip ties. Pole pockets are sleeves sewn into the banner's edges to accommodate poles for hanging, while reinforced corners add extra durability to the banner's corners.
