Real easy, the etiquette experts tell us. The general rule with utensils is to start from the outside of your place setting, and work your way toward the service plate (the main meal plate): soup spoon first, then fish knife and fork, then service knife and fork.
Soup bowl on plate
Bread & butter plate with butter knife
Dessert spoon and cake fork
Note that it often is recommended that the salad fork (J) is placed to the left of the dinner fork (I). However, in this formal setting the dinner fork is placed to be used before the salad fork because it is suggested that the guest awaits the main meal before helping him/herself to the salad.
Always use caution when working around the kitchen, stove and cutlery.
