The angle of this picture only shows one lantern, but there is another one on the other side of this door.
A few years ago, I was in a showhouse in Atlanta, and noticed that they had a lantern in the family room, instead of a chandelier. I thought this was striking and so beautiful. Since then, I have seen lanterns used inside with increasing frequency. Perhaps it is a trend, but I love the look it gives a room.
Ashley Whittaker also seems to like to use lanterns in her designs. Here is a boy's room designed by her, with a cheerful red lantern. Via Peak of Chic.
