Using these artificial hydrangea kissing flower balls is a breeze. For hanging, simply use the organza ribbon that comes with each ball. You can hang them on walls, in doorways, or from arches at your party. If you're using them for bouquets, just arrange them with other flowers as you like. For cake decoration, gently place them on the cake surface. When it comes to craft projects, get creative and attach them to different materials. As for maintenance, just use a soft brush or cloth to gently dust them off every once in a while. Avoid exposing them to direct sunlight for long periods as it may fade the color. Also, keep them away from sharp objects to prevent any damage to the silk material.
