To use these Baby Cthulhu posters and prints, simply find a nice spot on your wall and hang them up. You can use thumbtacks, adhesive hooks, or picture - hanging strips. Make sure the surface is clean and dry before hanging. When it comes to cleaning, you can gently dust the prints with a soft, dry cloth. Avoid using any harsh chemicals or abrasive materials as they can damage the paper and the inks. Keep the prints away from direct sunlight for long periods to prevent the colors from fading. Also, since frames are not included, if you choose to frame them, pick a frame that suits your decor style.
