Firstly, you will have to pick a variety of breads with different colours. Italian bread, rye bread and pumpernickel breads are used commonly in finger sandwiches. To add variety to the presentation, consider adding some tortilla wraps in there. Using spinach wraps or red pepper tortillas is an excellent way to enhance the looks.
Take a cutting board and cut portions of ham, turkey, roast beef and chicken into small pieces and layers. Now fill the sandwich with a thin layer of mustard or mayonnaise as per your liking. This will help the meat stick to the bread.
Start making up sandwich spreads with fresh or canned fish. Salmon, Tuna or salmon and brie and pimento spreads are commonly used for this purpose. Put a layer of lettuce on a big platter. After cutting the sandwiches into tiny and trimmed pieces of different sizes and shapes like square, triangular and rectangular. Remove the coating and cut the wrap sandwiches into 2 inch pieces.
Now it is time for you to neatly arrange the sandwiches on the platter. Make sure all the triangle sandwiches are facing upward so they can be easily distinguished. Use fruits such as strawberries, cherries and tomatoes to fill any other gaps.
