To put the picture of the car on the cake I printed off a coloring page.  I then used a size 3 tip and traced the car’s details with my buttercream icing and let it crust.  Once the icing on the cake had crusted too I was able to imprint the car onto the top go the cake and fill in the colors.

To ice the sides I did the petal technique. You put a decent dot of icing in a column up the side and then drag your small spatula through it.  There are quite a few tutorials for this fabulous technique!
