You’ve heard it before, it’s not broken, so I’m not fixing it. Odd numbers are the key in decorating. I think a stack of three is your best bet. Regarding your selection you have two options – color or subject. Maybe you get lucky and the two go hand in hand, For me, I selected three books on topics I love and as luck would have it, the colors worked out. (Personally I detest dust jackets, so it can be a surprise what color that actual book is). When going the route of decorating with a coffee table book remember one thing – less is more.
