Add confectioner's sugar. Mix thoroughly and add the oil of peppermint.
Knead with hands until fondant is smooth. Take out about 1/6 and color it green. Knead to mix color evenly. Cover with damp cheesecloth to prevent drying. Add enough yellow and red coloring to the rest of the fondant to make it a nice orange pumpkin color. Cover with damp cheesecloth.
Work with small amounts of the orange-colored fondant at a time and roll into small balls in the palms of your hands.
Break a toothpick in 2 and make grooves in the fondant like those in a pumpkin, using the broken end of the toothpick.
Roll a bit of the green fondant in thin cylinders and cut in short
stem like pieces. Press on top of the pumpkins.
