While many think of a family family room decorating theme as one with board games, and fluffy carpet, it can be much more. Family oriented living room decorating themes are common in home based decorating circles, and in most cases are similar in looks.

Using the sofa as a design anchor, the rest of this living room decorating theme should fall into place.
