Think Outside the Box when styling a bookshelf, don't limit your collection to the shelves. A framed picture or an object can be hung so they overlap, adding interest and allowing you to display larger items.
Coordinate With Paint Painting a bookcase's interior to coordinate with the room's décor adds a pop of colour. For a cohesive look, pull a colour from nearby upholstery, pillows or a rug.
Use Wallpaper Another great idea is to line the back of your bookcase with a gorgeous piece of wallpaper that coordinates with your space and draws your attention to the objects on display.
Vary Scale and Height Rather than lining up items of the same height, mix different heights by contrasting high and low to keep the eye travelling.
