To use your Sferra Giotto Full/Queen Flat Sheet, simply put it on your bed. It'll instantly add a touch of luxury. When it's time to clean, use a gentle cycle in warm water. Avoid using bleach as it can weaken the fabric and cause yellowing. Also, don't use fabric softener. Wash dark colors separately. 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.
