To use these Casey Cotton flat sheets, simply place them on your queen - sized bed. Smooth out any wrinkles for a neat look. When it comes to washing, you can use a regular cycle with cold or warm water. Avoid using harsh detergents as they might damage the fabric. After washing, tumble dry on a low - heat setting. Don't over - dry as it can make the sheets stiff. For long - term storage, make sure the sheets are completely dry and fold them neatly. This will keep them in good condition and ready for use whenever you need them.
