Sirkka is a light, unlined jacket with a detachable hood, long sleeves, and a zipper closure. The jacket features a high collar and large patch pockets with a side pocket and another pocket underneath the flap. The top half of the zipper is covered with a zipper shield with snap button closure. The overlapping pocket flaps with snaps create a fun little detail. The hood, hemline and cuffs are gathered with elastic cords. All seams of the jacket are sewn using flat-felled seams for a neat and durable finish..
Choose a light weight outerwear fabric. You can use your main fabric to line the hood or, if your fabric is very static or coarse, choose a separate lining fabric for it. Make sure to choose light snap fasteners: heavy-duty snaps might damage the light fabric.
