Using these napkins is easy. Just unfold them if needed and use them to wipe your hands or mouth during your event. When you're done, simply throw them away as they're disposable. There aren't any special maintenance steps. Keep them in a dry place to prevent the paper from getting damp. If you're using them outdoors, try to keep them away from direct water sources. Also, since the print is on one side, you can choose to use the printed side up for a more decorative look.
