Think of different patterns when arranging decorative wall ledges around a room. When you have two or more different lengths of ledges, arrangements that are staggered, diagonal, triangular or horizontal will add harmony and visual interest to your walls. Odd-numbered arrangements are considered more visually pleasing.
Create a random wall arrangement by staggering your decorative ledges across the wall in no particular order. Hang the longer ledges near the right corner of your wall, the medium-length ledges a few feet beneath it, and then the shortest ledges to the left of the others but spaced midway between them in height. Or, hang the shortest ledge in the middle of your wall, a longer ledge or two below it and a medium length ledge to the right of them. To create a corner focal point, mount two ledges so that the ends touch at a corner.
Add a methodical sense of movement to your wall by hanging your ledges in a diagonal line. They can be as far apart or close together as dictated by the amount of wall space available. You can create the line of ledges from the top left of your wall to the bottom right, or vice versa. And you can start with either your shortest ledge or the longest ledge at the top of the wall and work your way diagonally down.
Stack your ledges in a triangle pattern on your wall to add a sense of symmetry and balance to your room. Start with the shortest ledge on top, a medium-length ledge in the middle and the longest ledge on the bottom. You can also hang them in the opposite order with the longest ledge on top and shortest on bottom, but remaining in a tiered pattern. This technique works well when you have a small amount of wall space, as it keeps the ledges contained in one even pattern.
Hang your ledges in a horizontal line to spread them evenly across your room. To utilize wall space on different walls in your room, hang a ledge or two on each wall, but at the same height on every wall. If you are decorating only one wall, hang all ledges next to each other, either close together or a few inches apart, to create a smooth and systematic display.
