To make the butterfly decorations, mix the egg white and 1 3/4 cups powdered sugar until thick. Divide equally between 5 bowls. Color 4 bowls with different food coloring and transfer to 5 different piping bags fitted with very small tips. With a pencil, draw 10 pairs of butterfly wings on parchment paper, with curved lines as feelers on the top. Pipe around the wings and feelers (2 in each color, including the white) and decorate with dots in a different color. Allow to dry. Fold a piece of parchment paper into a accordion. Peel away the paper from the wings and feelers and place inside the paper folds. Stick together the butterflies by piping an icing 'body' between the wings. Allow to dry overnight.
