Using your red line icing, pipe the outline of the car and the window.Don’t forget to leave space for the wheels! These will need to be piped with your black line icing. Fill the car with red flood icing, then fill the windows and the wheel with black flood icing. Be careful not to over fill! Pop the biscuits back onto a baking tray and into the oven on the lowest temperature for 40 minutes. Your biscuits wont bake anymore, this helps to dry the icing. Using the image below as a guide, add your car frame using the red line icing. For the car lights add one yellow dot and one slightly bigger white dot on the bumper of your car. You'll now need to add the frame of your car window, following your original outline of the window use your white line icing to add this back in. To finish car biscuits add detail to the wheels and the door handle, using the yellow and white line icing. Leave to dry for 10 minutes at room temperature.
