1/4 sheet grooms cake. All ramps/jumps were cake. Covered in buttercream with fondant/gumpaste flags, tires and hay bales. I rolled a lego tire across the track to leave tire marks. Airbrushed the track darker brown. The hay bales were fondant covered in shredded wheat using gum glue. Cones were made by using a #10 tip as a mold. I pressed a lego tire into the side of the a fondnat circle to get the tire imprints. TFL.
