These Sferra Catena Standard Shams are easy to use. Just place them on your bed to add a touch of style. When it comes to cleaning, use warm water and a gentle cycle in the washing machine. Don't use bleach or fabric softener as they can damage the fabric. Wash dark - colored shams separately to prevent color bleeding. After washing, dry them on low heat in the dryer and take them out before they're completely dry. If you need to iron them, set your iron to the 'cotton' setting and iron on the back of the fabric.
