Colleen Whiteley has designed a shelf for the diehard paperback readers out there. Whiteley's Hold on Tight shelf is shaped like an "L" and uses a bright colored aluminium cube on an adjustable wing nut as a book end. The cube can be moved across the shelf to accommodate a growing or shrinking collection. If you’re one of the many who can't let go of those old novels, and somehow still manages to procure new ones from time to time, or you just like cool looking house wares, this shelf is for you.
