Using this Sferra Celeste Queen Bottom Fitted Sheet is easy. Just place it on your queen - sized bed. For maintenance, machine wash it in warm water on a gentle cycle. Don't use bleach as it can weaken the fabric and make it turn yellow. Also, avoid using fabric softener. Wash dark - colored items separately. Tumble dry on low heat and take it out while it's still a bit damp. You can steam iron it on the 'cotton' setting.
