These Sferra Catena Continental Shams are great for sprucing up your bed. Just put them on your pillows for an instant upgrade. When it comes to cleaning, use warm water and a gentle cycle in the washing machine. Don't use bleach as it can make the fabric weak and turn it yellow. Skip the fabric softener too. Wash dark - colored shams separately. Then, tumble dry on low heat and take them out while they're still a bit damp. If you need to iron, set your iron to the “cotton” setting and iron on the reverse side of the fabric.
