Using your Mi Zone Printed Sheet Set is a breeze. Simply put the flat sheet on top of the mattress, tuck in the fitted sheet around the corners, and place the pillowcases on the pillows. Your child's bedroom will instantly transform into a fun seafaring world. When it comes to maintenance, machine washing is the way to go. You can use regular laundry detergent, but avoid using bleach as it might damage the fabric and fade the beautiful whale prints. After washing, tumble dry on a low setting to keep the sheets soft and wrinkle - free. Always make sure to check the pockets of the fitted sheet before washing to remove any small items. This way, your sheet set will stay in great condition and provide comfort for a long time.
