The upper half of the surface of the walls can be pasted with the material of the same color, for example, lighter, and the lower one — by another. Better if the latter is darker in color. To divide them, you should use a decorative border. A similar method is suitable for rooms in a classic style. In living rooms, the wallpaper having a drawing is often glued in the upper part, and in stripes or plain — in the lower. But for the room where the child lives, it is better to place them in the reverse order — those who have a drawing from below, and plain from above.
