Using these sheets is a breeze. First, put the fitted sheet on your long single 50cm bed. The tags on each side will help you get the right orientation easily. Then, place the pillowcases on your pillows. For washing, you can use a regular laundry cycle with mild detergent. Don't use bleach as it might damage the high - quality cotton fabric. After washing, tumble dry on a low - heat setting to keep the sheets soft and durable. With proper care, these sheets will last you a long time and continue to provide a comfortable sleep environment.
