Using your Sferra Fiona Twin Flat Sheet is easy. Just lay it smoothly over your twin bed. When it's time to clean, machine wash it in warm water on a gentle cycle. Make sure not to use bleach because it can make the fabric weaker and turn it yellow. Also, don't use fabric softener. Wash dark - colored sheets separately to prevent color bleeding. Tumble dry on low heat and take the sheet out while it's still a bit damp. If you want the sheet to look shiny again, iron it on the 'cotton' setting. This way, your sheet will stay in great condition for a long time.
