Using these Casey Cotton Sheet Sets is a breeze. Just put the fitted sheet on your double bed 60cm, making sure to follow the tags for a perfect fit. Then add the flat sheet and pillowcases. For a great night's sleep, simply get in and enjoy the comfort. When it comes to washing, you can use a regular cycle in your washing machine. Use a gentle detergent to keep the fabric soft. Avoid using bleach as it may damage the cotton. After washing, tumble dry on a low - heat setting or hang them to dry. This will help maintain the durability of the sheets. With proper care, these sheets will serve you well for a long time.
