Decorating idea...things on walls

So here is a thought. If you don't like art or sunburst mirrors like the rest of us, it can be extremely confusing for you all to know exactly what to put on your walls. Something I have been noticing in the glossies lately are these gorgeous groupings of collections. Mary Macdonald, Miles Redd and the like, all use this clever trick for keeping the walls different and interesting. I'm totally into it.
