Using these fitted sheets is a breeze. Just place the sheet on your half - queen bed (60cm), aligning it with the tags for a perfect fit. When it comes to washing, use a gentle cycle with mild detergent. Cold or warm water is best to preserve the fabric's quality. Avoid using bleach as it can damage the cotton. After washing, tumble dry on low heat to keep the sheets soft and wrinkle - free. If you notice any loose threads, simply trim them carefully. With proper care, these sheets will last you a long time and continue to provide you with a comfortable sleep experience.
