Place your snowman biscuit onto a baking tray and into an oven set to the lowest temperature (50°C/gas mark ¼) for 40 minutes, or until the icing has set hard.
Once your flood base is set dry, use your black line icing to pipe a curved row of dots for the mouth and two dots for the eyes.
Use orange line icing to pipe the snowman's nose and green icing to pipe a band on the snowman's hat.
