Here's a great solution for modeling one of the most common trackside crops. Each cornfield set includes 400 1" (2.5cm) tall molded corn stalks. Simply place them on the base strips and build up a field to fit your scene. Each stalk has up to eight leaves and two ears. The set contains enough stalks to make a 100cm square field, plus flocking for the tassels and a base plate.
