Using these Casey Cotton Flat Sheets is easy. Just put them on your bed like you would with any regular sheet. To ensure a good night's sleep, make sure the sheet is smooth and wrinkle - free. When it comes to washing, use a gentle cycle with mild detergent in warm water. Avoid using bleach as it can damage the cotton fabric. After washing, tumble dry on low heat. This will help keep the fabric soft and prevent shrinkage. Also, try not to over - load the washing machine to ensure a thorough clean. With proper care, these sheets will last you a long time and continue to provide you with a comfortable sleeping experience.
