She wanted a model of the track the cars will actually run on. I cut the basic curve shape, she sanded until smooth. She also painted everything, including the tiny model cars. I cut the cars out of 1/4 inch plywood and shaped them up with a utility knife.
The miniature wheels are upholstery tacks and the lane strips are coffee stirrers. There is a cavity in the back for adding weights and everything is hot glued together.
Of course we'll try to win a few races but I hope she gets a design award.
