To use this quilt cover set, simply slip your quilt into the cover through the opening. It's perfect for a comfortable night's sleep. When it comes to maintenance, machine - wash it in cold water on a gentle cycle. Use a mild detergent to keep the colors vibrant. Avoid using bleach as it can damage the fabric. After washing, tumble dry on low or hang it to dry. Don't iron on high heat; a low - heat setting is best to maintain the fabric's softness and appearance.
