Spoons and knives are on the right, forks are on the left. Use them from the outside in. Solids like a bread plate or a salad are on the left, liquids like water, wine, or soda are on the right. Napkins belong unfolded on your lap. Use the napkin to blot your mouth.
Napkins stay off the table until the meal has ended.
If you must excuse yourself, leave the napkin on you chair. Pass serving dishes to the right to avoid table traffic jams. Make sure handles and serving utensils are facing the receiver. Spoon soup away from you, and do not crumble crackers into it. Keep your knife and fork on the plate if you are taking a break.
