Using your new Micro Fleece Sheet Set is a breeze. Just put the fitted sheet on your mattress, then lay the flat sheet on top and add the pillowcases to your pillows. When it's time to clean them, machine wash in cold water on a gentle cycle and wash them separately. Avoid using bleach as it can damage the fabric. Tumble dry on low and take them out of the dryer right away. Don't iron these sheets. If your washer or dryer doesn't have enough space for free movement, use a large - capacity commercial washer or dryer. With proper care, your sheet set will stay soft and cozy for a long time.
