Displaying state plates on your wall is a cool way to show off your collection and let others know where you've traveled. Others choose to use patterned plates or cascade a set of particular colors. If you ask us, we like to employ a little bit of humor with our vintage plates (which always gives the company a good laugh).
The shape of round plates also makes them easier to hang in a salon style grouping (without having to worry if they're even). If you don't like the look of an entire wall of plates, incorporate one or two into a grouping of art which will add additional texture and balance.
