Using your new novelty print sheet set is easy. Just put the fitted sheet on your mattress, smooth out any wrinkles, and then lay the flat sheet over it. Add the pillowcases to your pillows for a complete look. When it comes to care, these sheets are machine washable. Use a gentle cycle with mild detergent to keep them looking their best. Avoid using bleach as it may damage the fabric and fade the colors. After washing, tumble dry on low heat. You don't need to iron these sheets because they're naturally wrinkle - free. But if you prefer a more pressed look, use a low - heat setting on your iron. Keep your sheet set in a cool, dry place when not in use to maintain its quality.
