Using these sheets is a breeze. Just put the fitted sheet on your double - sized 60cm bed first, using the tags to make sure it's in the right place. Then lay the flat sheet on top and add your pillows. When it comes to washing, you can use a regular cycle in your washing machine with mild detergent. Avoid using bleach as it can damage the fabric. After washing, tumble dry on a low setting. These sheets are made to last, but to keep them looking their best, don't over - dry them. And always follow the care instructions on the label.
