Using these Sferra Estate king pillowcases is as easy as slipping them onto your pillows. They'll add a touch of luxury to your bed. When it comes to care, just toss them in the washing machine on a gentle cycle with warm water. Remember not to use bleach or fabric softener, or you might damage the fabric. Wash dark - colored pillowcases by themselves. After washing, dry them on low heat in the dryer and take them out while they're still a bit damp. If they lose their shine, you can use a steam iron on the 'cotton' setting to make them look brand - new again. Enjoy the softness and style of these pillowcases for a long time with proper care.
