To use this sheet set, simply put the fitted sheet on your king - sized bed first, making sure it fits snugly in the corners. Then lay the flat sheet on top. You can fold it over at the top for a neat look. Place the pillowcases on your pillows. For best results, wash the sheets before first use. Use a gentle cycle and mild detergent in cold water. Avoid using bleach as it can damage the fabric. Tumble dry on low heat to keep the sheets soft. Iron on a low setting if needed. Store the sheets in a cool, dry place when not in use.
