To use this quilt cover set, simply slide your duvet into the cover through the opening. It's a great way to instantly transform the look of your king - sized bed. When it comes to cleaning, you can machine - wash it on a gentle cycle with cold water. Use a mild detergent to protect the colors and the fabric. Avoid using bleach as it can damage the hand - painted designs. After washing, tumble dry on a low heat setting to keep it soft and fluffy. For long - term storage, make sure the set is completely dry and fold it neatly. Store it in a cool, dry place away from direct sunlight to prevent fading.
