In a mixing bowl, combine the softened cream cheese, chopped dill, lemon juice, garlic powder, salt, and pepper. Mix until smooth and well blended.

If desired, spread a thin layer of butter on one side of each slice of bread for added flavor.

Spread a generous layer of the cream cheese mixture on the unbuttered side of four slices of bread.

Layer the thin cucumber slices evenly over the cream cheese spread on each of the four slices.

Top with the remaining four slices of bread, cream cheese side down, to create sandwiches.

Gently press down on the sandwiches to help them hold together, then trim the crusts off if desired for a neater presentation.

Cut each sandwich into quarters or triangles, and arrange them on a serving platter.

Serve immediately or cover with a damp cloth until ready to serve to keep them fresh.
