Styling a bookshelf requires a little more effort than simply throwing knickknacks and hardbacks in one place and hoping for the best. It can take time to find the right balance and avoid an overly decorated display. Here are the bookcase styling pitfalls to avoid.

Only using books

It might sound intuitive to keep bookshelves strictly business, but decorative items are often the key to put-together shelf styling. Incorporating other objects not only gives shelves more personality but also creates a more well-rounded display. A small vase of flowers, a battery-operated lamp, special mementos and framed art can all come into play.

Mixing too many materials

Think about materials and how to keep a sense of cohesion. Mixing rustic elements like worn books with a pretty blown-glass vase can create the perfect juxtaposition, but mixing brass, wood, glass, leather, and ceramic all on one tiny shelf can lend a busy feeling that doesn't look quite right. When working with a wall of shelves, consider spreading the items out for a more cohesive display.

Getting the scale wrong

While it's best to have items of varying sizes, finding the right balance is key. To give smaller items more weight, group them together. As for large items, give them plenty of breathing room in order to keep the display from feeling too crowded.

Keeping it one-dimensional

The key to adding depth and interest to a display is layering. This can mean leaning a small framed print in front of a row of books or showing off a collection of candlesticks of varying sizes in front of a small mirror that's held upright on a display stand. Consider creating a stadium-like effect with taller items in the back and smaller items in the front, rather than having them all mixed together.

Not considering the back of the bookshelves

While the emphasis is certainly what's on the shelves, what's behind them matters too. Wallpaper, shiplap, or a splash of paint can all add personality behind book and decor collections. Good lighting can also help draw out these details that might otherwise go unnoticed. Illuminate shelves with library lights, small lamps and even candles (go for battery-operated if it's tight quarters) to show off back-of-shelf details.

Arranging items too close together

Allow items and collections to have their own moments. Creating space or breathing room throughout shelves allows a display to feel more harmonious and ensures each item or grouping gets its due. When shelves become too crowded, that's when you won't be able to appreciate those special items you're aiming to display.

Over-styling your shelves

In a world of #shelfies, stand apart from the crowd. Your books can take center stage even if they're not perfectly color-coded. Creating bookshelves that look perfectly styled takes restraint and a good eye, so give it time. Start with items that you love and want to take center stage to help you keep the focus. From there, add in additional items, little by little. If something doesn't feel quite right, take it out. Use your shelves as a space for collecting your most treasured items, and never forget to be on the lookout for new-to-you pieces to add to the display.
