Using these Casey cotton flat sheets is easy. Just put them on your single bed and enjoy a cozy sleep. When it comes to washing, you can use a regular washing machine on a gentle cycle with mild detergent. Avoid using bleach as it can damage the fabric. After washing, tumble dry on low heat or hang them to dry. To keep them in good condition, iron them on a low - medium setting if needed. These sheets are durable, but try to avoid sharp objects that could tear the fabric.
