Unit Three, Yellow Group, is all about knitwear and sewing with stretchy fabrics. Each of the four Lesson Modules focuses on a different type of stretch fabric, a different method of hemming stretchy fabric, and a different way to apply elastic. It is important to learn more than one way of doing things. As the student becomes more independent and creative with their own designs, a plethora of skills and techniques will be ready and waitng to be used.
