Shelf brackets are the perfect solution for creating shelf space where you need it without disturbing the rest of your living arrangements. Making them out of wrought iron is absolutely genius, not only for the strength of the material but for the unique and amazing designs that can be created. From simple angles to ornate filigree, wrought iron is both practical and beautiful. You can use your floating shelf (that's what it is called when it isn't attached to anything but the wall) to display special books, have a place to hang your favorite kitchen utensils, or to add a little storage to your entryway.
