To use your Sferra Giotto Full Fitted Sheet, simply place it on your full - size bed. The fitted design will keep it in place. When it's time to clean, machine wash it in warm water on the gentle cycle. Make sure to wash dark colors separately. Avoid using bleach as it can weaken the fabric and cause yellowing. Also, don't use fabric softener. Tumble dry on low heat and take it out while it's still damp. If you want to bring back its luster and sheen, iron it on the 'cotton' setting.
