Cucumber Sandwiches:
1. Cut cucumber into thin slices
2. In a mixing bowl, combine cream cheese, mayonnaise, and ranch mix
3. To assemble, spread cream cheese mixture and arrange sliced cucumbers on one slice of bread. Add fresh dill. Top with another slice and cut off the crusts. Then cut into fourths. 
4. Optional: Garnish with more dill and a cucumber slice on top of the sandwich

Arrange small bites & sweets on the rest of the tiered trays (I do believe there is an etiquette to this, with sweets on top, scones and cream in the middle, and tea sandwiches at the bottom, but I just told you we half-ass things around here, so do whatever you want.)
