Mirrors can also be used to create the illusion of more space. If you have a small long narrow hallway, why not place long mirror at the end (this makes the wall looks like it continues, it buffers an abrupt end. I also love grouping of mirrors when you have a wall you don't know what to do with. Why not take all different mirrors of all shapes and frames and create a focal point. This will look great over a plain sofa, or up a stairwell. Have you ever been in a room and it starts looking like a furniture showroom, its nice an everything is well-appointed, but it lacks something......PERSONALITY. Great design is more than matching colors, branch out and be bold add texture, whimsy, and an awesome mirror arrangement.
