Figure 9. Upper sleeve pattern. The width is the same as the top edge of the lower sleeve. Divide the width into quarters. The first quarter (A) marks the top of the sleeve. At the second and third quarters (B) and (C), mark slashes four inches deep (the same amount as you reduced the armhole of the body). Gussets inserted here and in the seam which runs down the back of the arm spread the top edge of the sleeve to fill the armhole.
