Place Names In Calligraphy

How do you produce place names for a formal occasion, such as a wedding, or an important dinner function?  It is quite simple to produce professional looking place names and it is relatively inexpensive to do.  All you need is some basic materials, such as some card, a ruler, some pencils and a calligraphy pen.  The card should be stiff enough to stand up when folded in half and left on a table.
