A sleeve joined to the body of a garment by a seam starting at the edge of the shoulder and continuing around the armhole. The sleeve head is typically cut larger than the armscye and eased in during sewing to create a smooth, rounded cap. This construction provides a tailored fit and a structured shoulder line.
Heard on the job
Pin the set-in sleeve carefully at the notch to distribute the ease evenly across the cap.
Insider tip
Baste the sleeve head with two rows of gathering stitches to control the excess fabric before pinning it to the armscye.
