Another idea for sectional wallpaper is to place it behind a sitting area, as pictured above. By simply using wallpaper in a corner like this, you can create the desired mood type for the seating area.
In this case, the large palm leaf patterns create a more casual feeling. It almost feels like a tropical Luau. The cold tones of the green also match the cold blue and faded purple tones of the chairs. So this idea shows how you can use sectional wallpaper to play with similar color tones.
