Using these Sferra Estate pillowcases is as easy as slipping them onto your pillows. They'll give your bed a touch of luxury. When it comes to cleaning, just put them in the washing machine with warm water on a gentle cycle. Remember, don't use bleach because it can make the fabric weak and turn it yellow. Also, stay away from fabric softeners. Wash any dark - colored pillowcases by themselves to prevent color bleeding. After washing, dry them in the dryer on low heat and take them out while they're still a bit damp. If they lose their shine, use a steam iron on the cotton setting to make them look great again. With proper care, these pillowcases will last you a long time and keep your bed looking elegant.
