To use this quilt cover set, simply slide your quilt into the cover. The large size is perfect for a super king bed, giving you plenty of coverage. When it comes to cleaning, it's best to follow the care label instructions. Usually, a gentle machine wash in cold water is a good idea.

After washing, tumble dry on a low setting or air dry to keep the colors vibrant and the fabric in good condition. Also, store it in a cool, dry place when not in use to prevent any mold or mildew growth.
