Avoid letting the napkin fall, never tuck it into your shirt, or use it to wipe your mouth before sipping a drink—these are etiquettes every diner should keep in mind.
The Elegant Way: 7 rules to wield napkins gracefully
Napkins, a crucial table companion, serve to shield attire from stains and to dab the mouth during meals. There are two main types: fabric napkins, meticulously folded, for upscale dining with multiple courses, and paper napkins, suitable for light meals or morning coffees.

Here are 7 guidelines for using napkins that every diner should remember:
Place the napkin on your lap when seated. If you're dining with the host, wait for them to unfold their napkin first, then proceed.
Unfold the napkin gently and assess its size. Never shake it loose. For larger napkins, only unfold halfway; for smaller ones, fully spread and cover your thighs.
Absolutely avoid wrapping the napkin around your neck or tucking it into your shirt. It's a surefire way to become the center of unintended laughter.

Use the napkin to wipe your mouth before sipping a beverage. This prevents food particles from clinging to the rim of your glass.
Napkin rings add an extra touch of elegance to the table setting. When removing the napkin from the ring, place it above on the left and fold the napkin into the ring, returning it to its original position after the meal.

When temporarily leaving the table, neatly fold the napkin, placing it on the chair or to the left of the plate.
Conclude the meal by folding the napkin and placing it near the plate, concealing the used portion discreetly.
