A room that is way too perfect, like out of a design school book, will be boring to live in, but the element of surprise does need to be compatible with the rest of the decor. For example, a few antiques in an otherwise contemporary setting is a welcome visual change. All accessories, be they personal treasures or objects chosen specifically for the room, should be compatible with the decorating scheme. The items should relate in some way to the color plan and the overall mood of the room. Books and art are good starters.
Books are always a welcome decor.
They display the interests of the owner as well as make the room feel homey. Fine art stands alone and will always enhance a room. Family photos are always welcome and certainly add a personal touch. Framing is important as the art of the frame should compliment the space it shares as well as the picture it displays. Next, look to scale and balance.
