If you are looking to change your homes decor to that of a Mid-Century modern style, there are a few design secrets you should know before getting started.
First off I suggest, if you haven't already, set aside some time for researching this unique design. Get a feel for the architecture of that era, the interior design principles, and the overall mindset and motivations behind the design. Familiarize yourself with every aspect of the movement. Study pictures and floor-plans and get a well versed understanding, and feel, of the overall look that defines the style and period.
Remember that Mid-Century modern design is marked by the minimalist attributes of clean, simple lines and neutral, monochromatic colour tones, along with "minimal" clutter. Stay away from overcrowding or overdoing a space. Less is best when it comes to Mid-Century modern design.
If you are on a limited budget but still really want original pieces, you could check at auctions, flea markets, estate sales and thrift stores. You may be pleasantly surprised at what gems show up for a real bargain. I'm not saying you will find designer originals but you may uncover some quality reproductions produced during that era.
While there seem to be many rules that govern Mid-Century modern interior design, don't allow yourself to be bullied into creating a design that is boring or generic. Always make sure you put your personal stamp on your designing. You want your surroundings to reflect your personality and flare while staying within the design parameters of that era.
