Decide if the room will receive a complete decorative overhaul or simply a new leather couch. Recycle furnishings that are already in your living room to reduce decorating costs.
Select a color scheme. Browse interior design magazines and home style magazines for ideas on how to play with color. For example, match your leather couch to the color of your walls for a monochromatic color scheme or mix and match colors for a vivid color scheme -- some bold, some neutral.
Dress up your walls. Play up leather's natural beauty and earthy quality by hanging bamboo blinds or natural linen curtains. Natural or rustic wall art prints also enhance leather's natural quality.
Add a splash of color or animal print to your floor. Place fluffy rugs or faux fur on the floor in front of your leather couch. Choose a bold color like red, or break up a monochromatic room with an animal print.
Add accent pieces to complete the look of your living room. Consider ways to recycle furnishings. For example, fill a display vase with artificial or fresh cut flowers or fill a set of rustic Terra cotta pots with green plants. Incorporate as many natural pieces as possible to play up the natural look of your leather couch.
