Using this quilt is easy. Just spread it on your king - size bed and enjoy a warm and cozy sleep. 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 option. Avoid using harsh detergents as they may damage the down and feathers. Also, make sure to dry it thoroughly on a low - heat setting. Store it in a cool, dry place, and if possible, use a breathable storage bag to keep it in good condition.
