I came across the picture above while browsing Facebook (although I can't remember who posted it) and I think it epitomizes that perfect union. Notice the crustiness of the cast iron fireplace surround sitting directly across from the sleek acrylic cocktail table. Look to at all the fresh live greenery in contrast to the wicker chairs and native stone walls. The complimentary blue and green absolutely sing. There is texture upon texture, like the brick floor, sisal rug and patterned rug and rough hewn side table.
Take a lesson from this picture. I think you can learn a lot about creating the perfect combo in your home.
