Using your Sferra Giotto Twin Duvet Cover is easy. Just slide your duvet inside and enjoy the soft, smooth feel. When it comes to cleaning, machine wash it in warm water on a gentle cycle. Make sure not to use bleach as it can damage the fabric and make it turn yellow. Also, avoid using fabric softener. Wash dark - colored covers separately to prevent color bleeding. After washing, tumble dry on low heat and take it out while it's still a bit damp. If you want to bring back its shine, iron it on the “cotton” setting. This way, your duvet cover will stay in great condition for a long time.
