To use these 'Soul of Korra' posters and prints, you can hang them on your wall using common hanging tools like nails or wall hooks. Just make sure to choose a proper spot that suits your room's decor. When it comes to maintenance, keep them away from direct sunlight to prevent the colors from fading over time.
