In a bowl, place 6 ounces of the white fondant and add 3 drops red gel food coloring and 2 drops of yellow gel food coloring. Gently fold together until fondant is of even orange color to resemble Tigger’s face.
Sprinkle a clean work surface and a rolling pin with cornstarch. Using the rolling pin, roll the orange fondant to be about ¼ of an inch thick.
Using the largest cookie cutter, cut out 12 circles and place on a baking sheet lined with wax paper.
Shape the remaining orange fondant into 24 small circles to resemble Tigger's ears. Set aside.
In another bowl, place 1 1/2 ounces of white fondant and add 2 drops of yellow gel food coloring. Gently fold together until fondant is evenly colored. Using a rolling pin, roll out the yellow fondant to about ¼ inch thick.
With the medium cookie cutter cut out 12 circles and with the smallest cookie cutter, cut out another 12 circles.
With the smallest cookie cutter, cut out a small portion off the middle-sized yellow fondant circle into a crescent shape.
In another bowl, place the remaining white fondant and add one drop of red gel food coloring. Gently fold until of even pink color. Roll out the pink fondant into 12 small spheres and flatten slightly to resemble Tigger’s nose.
To assemble Tigger’s face, brush water on the back of each piece and gently press onto the large orange circle to secure.
Using the black decorating frosting, draw eyes, eyebrows, and tiger stripes on the assembled face.
With a piping bag, frost each cupcake and carefully place fondant Tigger face on top.
