A well-curated bookshelf is something of an art form. A visually compelling mix of books, photos, objets d'arts, small oil paintings, stones from the beach adds a bookish and bohemian vibe to any room. Some examples of shelves we admire.
Place painted foam board in the back of the bookcase, giving the look of a painted bookshelf w/out the commitment. Love this idea for a small book shelf next to couch. Good way to use yellow without committing to it in a big space.
