A round mirror makes a great statement. It softens a square regimented room and adds a touch of drama. Mirrors add to a bathroom and dress up a mantle piece.
A black one – especially a convex one – adds a stunning feature to a white wall.
IKEA makes a gorgeous timber one which could make a great light trick highlighting a great feature of your home. A view or pretty outside plant or tree can be reflected, or a favourite ornament can be shown off. Make sure not showing things you don’t want to see – i.e. the roof !!
The trick is to hang them lower than you would a painting and at a place to show off the best features.
Play around and add more than you bargained for.
