Abstract
Abstract Shelves are disclosed having slots cut in their ends, into which are threaded straps comprising loops of webbing. Top-straps are for supporting the topmost shelf from a wall, and shelf-straps are for supporting a shelf from a shelf above. The modularity of the pre-formed loops permits a very versatile system. Long shelves are also shown with T-slots by which the shelf can be supported intermediately.
