Using these Casey cotton flat sheets is easy. Just put them on your long single bed and enjoy a comfortable sleep. When it comes to washing, use a gentle cycle with mild detergent. You can wash them in warm water, but avoid using bleach as it might damage the fabric. After washing, tumble dry on a low setting. Make sure to iron them while they're still slightly damp for a smooth finish. If you want to store the sheets, keep them in a dry and cool place, away from direct sunlight. This will help maintain their quality and color over time.
