this home theatre is a great example for horizontal lines. the design behind the TV as well as the shelf under the TV and even the white wall is all horizontal and calming. a perfect idea for a home theatre room.
This is a good way to make a bigger TV look intentional (and less like your husband won over you). Keep it alone on the wall above the console or shelf and hang another shelf above it. (design by Sarah Richardson) - Home Decor Idea
