These Sferra Fiona pillowcases are super easy to use. Just slip them onto your pillows and enjoy the softness. When it's time to clean, machine wash them in warm water on a gentle cycle. Make sure to wash dark colors separately. Don't use bleach as it can weaken the fabric and cause yellowing. Also, avoid using fabric softener. Tumble dry on low heat and take them out while they're still a bit damp. If you want them to look extra shiny, iron them on the 'cotton' setting.
