Using this quilt cover set is easy. Just slip it over your king - sized mattress and pillow. To maintain its beauty, machine wash it in cold water on a gentle cycle. Use a mild detergent and avoid bleach. When drying, tumble dry on low heat. This will keep the colors vivid and the fabric soft. Don't iron directly on the poppy flower design to prevent damage. Also, store it in a cool, dry place when not in use to avoid any mildew or stains.
