Using these sheets is easy. First, take out the fitted sheet and use the tags on each side to make sure it's placed correctly on your long single bed (60cm). Then, put your pillows into the pillowcases. For best results, wash the sheets in cold or warm water before first use. When it comes to regular washing, use a gentle cycle with a mild detergent. You can tumble dry on low heat, but avoid high heat as it may shrink the fabric. Don't use bleach as it can damage the color and quality of the cotton. If there are any stubborn stains, spot - clean them gently before washing. With proper care, these sheets will stay soft, comfortable, and durable for a long time.
