I apologize that no one has responded to your question sooner. Different experts
come online at various times. I just came online and saw your question. I suspect the reason no one answered is that your question is rather complicated, and requires a diagram to explain everything.
There are a few general rules, including to make sure everything is symmetrical. The centerpiece should be exactly at the center of the table. The plates need to be an equal distance from each other. Knives go to the right of the plate, with the knife to be used first farthest from the plate and the blades of all the knives face the plate. Forks go to the left, with the first fork to be used, farthest from the plate. However, the dessert fork goes at the head of the plate. Spoons go to the right of the knives.Again, the one to be used first, farthest from the plate. The dessert spoon goes at the head of the plate.
The glasses are placed above the knives. The water glass is closest to the plate. Next is the red wine glass, then the white wine glass, the sherry glass and last, champagne glass. The coffee cup is always placed to the right of the dinner plate.
