To use this quilt cover set, simply slip your quilt into the cover through the opening. Make sure it's evenly spread inside for a smooth look. When making your bed, tuck the edges neatly under the mattress for a crisp appearance. As for care, it's best to machine - wash it in cold water on a gentle cycle. Use a mild detergent to keep the colors and patterns vibrant. Avoid using bleach as it can damage the fabric. After washing, tumble dry on low heat or hang it to dry. This will help maintain the quality of the quilt cover set over time.
