This is perfect for the huge, blank wall facing the 8' long built-in sink, vanity and wall-to-wall mirror in the first part of my bathroom.  I needed something decorative and relatively flat, so that one could easily pass through this area to get to the adjacent shower/toilet area.  
 The huge mirror over the sink reflects the wall hanging, so anyone using the sink is not facing the reflection of a blank wall, but of a sculpture.
