Using your Sferra Giotto Twin Flat Sheet is a breeze. Just put it on your twin - sized bed and enjoy its softness. When it's time to clean, use a gentle cycle in warm water in your washing machine. Don't use bleach as it can weaken the fabric and make it turn yellow. Also, avoid using 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. If you want to bring back its luster and sheen, iron it on the 'cotton' setting.
