Picture ledges are perfect above a couch or sofa that's against a wall. You can arrange them one ledge directly above another or staggered. If you choose to stagger them, adding a piece of art in the blank space is a good idea so the arrangement doesn't look off-balance.
Picture ledges aren't only for pictures. Put them in a nursery or child's room and use them as book ledges. When your child has outgrown picture books, the ledges can be used to display their school artwork, achievement certificates, and photos of family and friends.
If you have a bold wall color, use a couple of white picture ledges to break up the saturated color. If you go with white picture frames or mattes, your artwork will also pop more against the darker wall.
Who says you can't fill a wall with picture ledges? With a white wall and white picture ledges, the items on the ledges really pop. You could execute this idea in a child's room or playroom. This would also look great in a hallway or landing.
Picture ledges are also great for displaying collections like plates. It doesn't make sense to buy pretty plates and store them away where no one can see them. So put patterned plates front and center -- and high enough so they aren't within reach of little hands.
