In addition to all artwork in the restaurant being on back to front canvases, the mirror in the bathroom was a collection of different size canvases with mirrors inside. Genius! This is definitely an idea to steal..
different size canvases,
cut to size mirrors (not as expensive as you might think)
attachments to the wall
I think this is also a great way of creating a large mirror. It wasn’t just the mirrors I liked. The industrial style bathroom was also really smart.
