When setting tablecloths on dinner tables what does the term centered or centerfold mean?

In the context of setting tablecloths, the term "centered" or "centerfold" refers to the technique of folding the tablecloth to ensure it is evenly distributed and aligned in the center of the table. This involves placing the midpoint of the tablecloth at the centerline of the table, allowing equal lengths to drape over each side. Proper centering enhances the visual appeal and ensures a neat presentation for dining.
