To use these posters and prints, first choose a suitable spot on your wall. You can use wall - hanging tools like nails or adhesive strips. Just make sure the surface is clean and dry before hanging. When it comes to cleaning, use a soft, dry cloth to gently wipe off any dust. Avoid using water or cleaning agents as they might damage the print. Store the prints flat in a cool, dry place if you're not using them right away. Also, keep them away from direct sunlight to prevent the colors from fading over time.
