This pattern has been graded according to ASTM sizing standards and guidelines. But most women are not standard! Before beginning this project, take a close look at the schematic and make note of the measurements of the various parts of the finished item. You may wish to adjust some of these measurements to obtain a sweater that fits you and your unique body.

This pattern is made in one complete piece for the body. Neck and sleeves are crocheted directly onto the body.
