Using your Sferra Estate Twin Duvet Cover is easy. Just slip your duvet inside it and enjoy a comfortable sleep. When it comes to maintenance, remember to machine wash it in warm water on a gentle cycle. Don't use bleach as it can damage the fabric and make it turn yellow. Also, avoid using fabric softener. Wash dark - colored duvet 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 it loses its shine, use a steam iron on the “cotton” setting to bring back its lovely look.
