I put the mercury glass candle holders on the sconces because I felt the big wall needed more reflective surfaces and because I have other mercury glass scattered around the room so it kind of pulls it all together.
Forgive this picture. I took it real quickly on my phone and it is a bit fuzzy even to my old eyes, but you get the idea.
And then, because I was getting tired, I simply hung the two mirrors in the first guest room. This room has a Mediterranean feel and so do the mirrors. I know, one is round and one is square...it's my house...and they are up and out of the way for awhile - at least until the next "simple" move of something. Stay tuned..
