How do you arrange decor on a console table?
There is a general rule of thumb when decorating, use odd numbers. So if you are going to add small vases or candlesticks use odd numbers.
Another great idea is to use symmetry or asymmetry. For example, the look of having two lamps at each end is very pleasing to the eye. Or have one large lamp/vase on one end with a large piece of artwork on the other.
