Unless noted, the seam allowance included is 3/8″ (1 cm) for joined seams.

Clip or mark the notches. Notches are indicated on the pattern by “T” marks.

The Den Jacket Collar is shown notched.

Before handling your cut pieces too much, sew a stitch line 1/4″ (0.6 cm) away from the fabric edge on the front upper and back yoke pieces at the neckline. This will prevent your neckline from stretching out before attaching the collar.

Staystitching is shown on Den Jacket Sewing Pattern Pieces

If lining your jacket, you can also staystitch your lining pieces.

Lining pieces for the Den Jacket sewing pattern are staystitched


Attach the fusible interfacing to the wrong side of the under collar, side pocket facings, the top of the patch pockets and half of the center front placket (on the long side without a middle notch. The center front placket fusible will be set inside the seam allowance.

The fusible will help stabilize the collar, pockets and the center front where you will add buttons or snaps. Tricot fusible interfacing is recommended, but you can use any lightweight fusible interfacing.
