Jasika Blazer - by Closet Core Patterns
Paper Sewing Pattern

The Jasika Blazer is a classic tailored jacket with a semi-fitted shape that will never go out of style. With just the right amount of polish and detail, Jasika is a wardrobe workhorse and a mighty skill builder. Our instructions use modern speed tailoring methods, fusible interfacings and minimal hand sewing to make tailoring fun and accessible for everyone; make a blazer you'll want to wear forever!

This jacket is fully lined and features a classic notched collar, single button closure, back vent, shoulder pads, welt pockets, gorgeous two-piece sleeves and a flattering shape that skims the curves of the body. Optional details include pocket flaps, topstitching, decorative sleeve cuff buttons and leather or suede elbow patches.

Suggested Fabrics: For the jacket body: medium to heavyweight suitings or lightweight coatings with surface texture such as wool melton, wool flannel, crepe and tweed. Velvet, medium-heavy weight cotton, seersucker and linen may also be used. Please note: tightly woven, smooth surfaced suitings like wool gabardine are not recommended since they can be difficult to fuse using an iron.

For the lining: rayon bemberg, charmeuse, crepe de chine, silky cottons like voile

For the pockets: sturdy cotton like shirting, quilting cotton or muslin (1/4 yd / .25m)
