Using your Sferra Giotto Twin Fitted Sheet is easy. Just fit it onto your twin - size bed. When it's time to clean, you can machine wash it in warm water on a gentle cycle. Make sure not to use bleach as it can weaken the fabric and cause yellowing. 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 damp. If you want to bring back its luster and sheen, you can iron it on the 'cotton' setting.
