9. Use symmetry. When you're striving for a symmetrical balance, clutter will throw it off and stick out like a sore thumb. This can help you edit your items.
In a living room, consider placing two chaises so they face one another. You can lie down to read a magazine when you're alone, but still feel comfortable inviting company to sit down because the back provides the traditional support of a sofa.
Like the symmetry, one armed sofas, wall colour and accents such as over sized vases compliment the sofas. Like the large palm, black framed painting and black shades on lights.
