If you are looking to add elegance and inspiration to your living room, worldly decor will definitely accomplish that. One way to go would be to utilize maps from all over the world. Old world and antique styled maps work great in a traditional decor style and more contemporary maps with famous sayings or photographic overlays are a great way to add a worldly decor style in a more modern living room.
Another theme you could go for is to make a collage wall of several different pieces. When you create a collage wall you want all the artwork to be different sizes and sometimes different shapes. It does not all have to have the same color frame or be the same dimensions. Use a mixture of rectangles and squares, big and small. This will add depth and dimension to your room and create a fun yet elegant space. The collage wall shown in the picture uses all different colors of frames and pieces of artwork. It ties the room together beautifully and doesn't make you decide on just one or two of your favorite pieces. Using oranges, yellows, red, and browns together is not only gorgeous but it is also very versatile. You can choose any earth toned color wall, furniture, and accessories to play off of these colors.
Lastly, some individuals may just be interested in the simple beauty of landmarks or international destinations. To help transform your living room to reflect this, you can hang artwork that includes architecture, bodies of water, tropical beaches, mountain ranges and other aspects of nature or history from famous locations. Achieving this look will help the room feel very relaxing and beautiful.
