Using your Callista duvet set is a breeze. Just spread the duvet on your bed and place the shams on your pillows. It's perfect for a casual and relaxing bedroom. When it comes to cleaning, you can simply throw it in the washing machine. However, make sure to follow the standard washing instructions for cotton - linen blends. Avoid using harsh detergents as they may damage the fabric. After washing, let it air dry or tumble dry on a low setting to maintain its shape and texture. With proper care, your duvet set will stay in great condition for a long time.
