Much as I love mirrors, I've learned to really pay attention to where I hang them. They really do have a function. They can be hung to reflect something pretty, like the light of a beautiful chandelier. (But make sure they don't reflect the people eating.) Or to double the impact of a vase of fresh flowers or it candles.
They can be hung where they are useful. Bathrooms are the most obvious of these places, but what about entry halls? Isn't it nice to do a quick check before you go out the door? Or perhaps the entry is on the small size. Nothing like a mirror to open up the space and make it feel larger and lighter.
And they can be used as art. But even as art, unless you are doing something fun like this creative grouping from Real Simple, be very careful what the mirror reflects.
Placing mirrors on mantels can be a great idea - as long as the ceiling isn't reflected. And that dining room mirror? Hang it high enough so the chandelier is reflected, but not the diners (unless you aren't sure you have enough to feed everyone). Above the sofa? Maybe.......as long as the main thing you see is yourself - or others - walking by. It may be that an eye-catching piece of art is a better idea.
