It's definitely true that if you don't occasionally rotate your art collection you don't appreciate the pieces. They just blend into the wall and you ignore them. So I bought in a few new prints & mirrors and moved everything around.
But I hated the arrangement so now my art wall looks like this:
I decided that I would prefer to hang one large photograph or piece of art in an oversized vintage frame over the sofa.
A few of the framed prints found new homes like this Baby Crane by Sharon Montrose. I'll enjoy her more here plus she's also covering that eye sore of a unused phone jack.
