Using these Casey Cotton Flat Sheets is easy. Simply put them on your Super King bed. You'll immediately notice how comfortable they are and how they help you sleep better. When it comes to washing, just toss them in the washing machine. Use a gentle cycle with mild detergent. Don't use bleach as it might damage the fabric. After washing, you can tumble dry them on a low - heat setting. If you want them to look extra smooth, you can iron them on a medium - heat setting while they're still a bit damp. These sheets are durable, but try to avoid sharp objects that could tear the fabric. With proper care, they'll serve you well for a long time.
