Hi.  Where can I find a rolling pin that has a texture that I can use for a car cake?  I want to use it to make a grill on the car.  Thank you.

I doubt that you'll find such a specialized piece of equipment, especially because car grills vary so much.

I use a modeling tool, a smooth thin paint brush handle, a toothpick, or the back of a thin knife blade to re-create the design.
