When it comes to the geometry of interior design, rectangles are king. Perhaps that is why I love the look of round mirrors so much. Circular mirrors provide a striking contrast against the sharp angles of a desk, table or fireplace.
What's not to love about the circle? After all, it's the first shape we recognize as newborns. There is a natural and organic feel to round mirrors. But at the same time, the round mirror is a bold visual stamp on the wall, less like a window and more like an eye. A rectangular mirror fits into a room: A circular mirror punctuates it.
