Does anyone make placards/category dividers for DVD collections? To be more specific.... Heavy plastic dividers that come with letters to write either STUDIO or GENRE, used to properly categorize your collection. I am sure you know what I am talking of -- you see them in video or music stores all the time. Would love to get a dozen of these dividers so I can easily categorize my collection and see the divides from across the room. Anyone knows who makes these things? Thanks in advance!
