I order unsliced bread at the bakery. I think take off crust and slice it in sheets long way... I spread softened cream cheese on each layer of the bread and put something different on cheese each layer - for sweet tea sandwiches I put maraschino cherries on one layer, raspberry jam on the next and crushed pineapple (very well drained). I then cut into rectangles and half those again.
For savory tea sandwiches: again cream cheese base and each layer something different - green olives, cucumbers, red pepper slices.
