Using your Sferra Celeste Twin Flat Sheet is easy. Just put it on your twin bed and enjoy the soft and crisp feeling. When it's time to clean, machine wash it in warm water on a gentle cycle. Remember not to use bleach as it can damage the fabric and make it turn yellow. Also, skip the fabric softener. Wash dark colors separately to prevent color bleeding. Tumble dry on low heat and take it out while it's still a bit damp. Then, if needed, you can steam iron it on the 'cotton' setting. Following these steps will keep your sheet in great condition for a long time.
