Whilst maintaining themes throughout your space, make sure that you do not add too many, and also that there are not too many dominant pieces in any given space. By their very nature, the quality of a natural wood finish can be very alluring and eye-catching, so avoid using tons of this material everywhere.
Almost everyone loves a spacious room, and if your room is small then you just have to do something about it. You can make your room appear bigger by placing mirrors in strategic positions. Doing this will increase the width and the breadth of your living room from the reflection.
This is not to say that all items need to be made in the same period, have the same texture or be of the same color, but instead that you should stick with a few themes and make sure that one or two are reflected in each and every piece of furniture that you have in your living room.
