Large geometric shapes with bold colors on rugs or throw pillows are reminiscent of mid-century modern decor. While the sofa may be one solid color, add punches of color using the rug or pillows in different shapes to bring in your decorating style. It may give off a retro-kind of look when you are done decorating, but know that is part of the decor. As I said before, while you may not like ALL the aspects of one style, you can certainly mix and match mid-century modern with more modern pieces.
Artwork is another way to show off your mid-century modern vibe. Use bold colors to help pick out canvas or printed artwork or embrace the gold and use it in metal artwork pieces. Either way, you can’t go wrong. Notice that most artwork will incorporate the geometric shapes whether it’s circles, triangles or squares so you know you are on the right path.
