Using your Sferra Estate duvet cover is simple. Just put it over your duvet insert and you're all set to enjoy a comfortable sleep. When it comes to maintenance, always machine wash it in warm water on a gentle cycle. Make sure not to use bleach because it can damage the fabric and make it turn yellow. Also, don't use fabric softener. If you have dark - colored covers, wash them separately to prevent color bleeding. For drying, use the low - heat tumble dry setting and take it out while it's still a bit damp. To make it look shiny again, you can use a steam iron on the “cotton” setting. With these steps, your duvet cover will stay in great condition for a long time.
