Using these Casey cotton sheets is a breeze. Just put the fitted sheet on your long single bed (60cm) first, using the tags to make sure it's in the right place. Then add the flat sheet and your favorite pillowcases. For a great night's sleep, tuck the edges of the flat sheet under the mattress. When it comes to washing, use a gentle cycle with mild detergent in warm water. Avoid using bleach as it can damage the fabric. After washing, tumble dry on a low - heat setting. This will help keep the sheets soft and maintain their durability. And remember, don't over - dry them, or they might shrink a bit.
