    Creating a Balance

    Distributing equal visual weight in a room is very important. Maintaining a balance thus becomes significant when we place accessories in different rooms but in the same way. Many of us are usually comfortable with this, but sometimes balance is also achieved by placing dissimilar objects which have equal eye attraction. Thus sometimes even a casual setting can be more lively than ordinary and otherwise stiff arrangements which are easy to setup as to a formal setting.
