Decorative wall shelves can be bought already put together. This sort of package includes the top of the shelf, the brackets, and even matching screws. Buying shelving like this is probably the most popular way to go. These pre-packaged decorative wall shelves are simple and leave no room for error. Just check some of them out at your neighborhood hardware or home improvement store, you may be pleasantly surprised with how easy they are to install.
Floating shelves look fragile to the naked eye because of the way they sit on the wall. All the workings of the brackets are hidden so it seems as though they are floating there on the wall. In reality they are usually much stronger than other types of shelves which are supported with traditional brackets and screws.
