Trillium uses both sport and worsted weight yarn in the design. The front and back panels use two colors of the sport in a slip st pattern and the sides and sleeves are picked up and knit sideways in a coordinating worsted. Yardage requirements for the sport - dark 700 and light between 350 abd 700. Worsted requirements between 440 and 660.
