The difference between appetizers and hors d’oeurves is appetizers are served at the table and hors d’oeurves are served away from the table.
Always prepare ahead with small plates, napkins, cocktail knives or individual forks (usual 2 tines) to allow your guests to serve themselves and have on hand, all the ‘equipment’ needed to comfortably handle this course.
If it is a Wine and Cheese event only, watch to make sure no one leaves your home over the legal driving limit. Have a pot of freshly made coffee and perhaps something to eat. If you have to, drive them home. They will thank you for caring.
