Meet your instructor, Kathleen Cheetham, and learn more about the practice and purpose of pattern grading. Kathleen discusses the tools you'll need and explains how pattern grading can benefit you as a pattern maker or home sewer.

If you found a multi-sized pattern you like, but its smallest size is still too large, you can grade it down one or two sizes using tools as simple as a business card, straight edge and French curve. Kathleen walks you through the process of grading down a bodice by one size, both back and front. You'll see how to tackle tricky points like the armscye and neckline, and how to grade down notches, tucks and darts.

The same principles for grading down a size can be used to grade a pattern up two sizes. Kathleen demonstrates how to grade a pants pattern up by two sizes, including moving the crotch point, adjusting darts and marking pocket notches. Then learn how to handle details such as a pocket or waistband.
