To use these 'Believe in Fairies' posters and prints, first find a nice spot in your room. You can hang them on the wall using regular wall hooks. If you want to make them look fancier, you can buy a frame separately and put the print in it. When it comes to cleaning, just use a soft, dry cloth to gently wipe the surface. Avoid using any wet or chemical - based cleaners as they might damage the print. Also, try to keep the prints away from direct sunlight for long periods, as this can fade the colors over time. With proper care, your 'Believe in Fairies' poster or print will stay beautiful for years.
