Using these artificial calla lilies is super easy. You can put them in vases to decorate your living room, or use them to make beautiful flower arrangements for weddings and parties. Just arrange them as you like to create a lovely scene. When it comes to maintenance, if they get dusty, you can gently use a soft brush or a hair dryer on a cool setting to blow the dust off. Keep them away from sharp objects to avoid scratches on the poly foam flowers. And store them in a dry place when not in use to keep them in good condition.
