Great advice. You are right on target GYPSY. Buying the bulk of your basics finger foods, meatballs, chick livers, miniature drumsticks, egg rolls... etc then supplement each of them with your own great dipping, and scooping sauces. You will be an absolute winner.
If make a few special dipping sauces and decorate your table with wonderful stuff like flowers, feathers, assorted bright vegetables (left whole) all kinds of fruits, and cheeses, floral greens.. figurines, even mirrors, you will set a new standard in party planning I'll dig up some real dipping diamonds for your party... Good Luck
