Using your Sferra Estate Full/Queen Flat Sheet is easy. Just lay it on your bed, align it with your Grande Hotel White fitted sheet, and tuck in the edges. When it comes to cleaning, machine wash it in warm water on a gentle cycle. Don't use bleach as it can damage the fabric and make it yellow. Also, don't use fabric softener. Wash dark - colored sheets separately to prevent color bleeding. After washing, tumble dry on low heat. Take it out while it's still a bit damp. If the sheet loses its shine, use a steam iron on the “cotton” setting to make it look fresh and shiny again.
