To use these Casey Cotton flat sheets, simply put them on your queen - sized bed. They're so soft and breathable that you'll feel great as soon as you lie down. When it comes to washing, you can toss them in the washing machine on a gentle cycle with mild detergent. Avoid using bleach as it might damage the fabric. After washing, tumble dry on low heat.
