Now that the room is painted you have all of the accessories waiting to be placed, but where to begin.
First, decide if all of the existing accessories will be used and if any new ones will be added. Then start preliminary groupings of the accessories to be sure that it is going to work the way you want. This keeps nail whole repair to a minimum. Make sure when grouping your items they are in odd numbers (one's, three's, five's, etc). This gives your décor that finishing touch and professional finish.
Now that your accessory arrangements have been grouped, think about placement. There are four ways in which arrangements are done: symmetrical, asymmetrical, radial, and stepped.
A quick example of each grouping style. Symmetrical: A sofa with the same lamp and end table flanking each side. Asymmetrical: A mantel with a tall item on one side and shorter item on the other. Radial: Wall grouping with objects stemming from a central point and coming out in a circular fashion. Stepped: A group of pictures as you head up a staircase.
If you can't decide on one arrangement style no worries, you can mix and match. But, don't get carried away. I suggest only doing two in a space, especially to start with.
Last, keep in mind visual weight. Even though objects may not weigh a lot on a scale, they may look like they do. If you had a large picture hung it would look heavy compared to a smaller picture. In order to balance these pieces out you would need to hang the large picture with a grouping of smaller ones next to it.
When arranging your accessories remember odd numbers of objects in a group and to have the visual weight balanced, for harmony to be achieved throughout your space.
