Buy the Heather Blazer sewing pattern from Friday Pattern Company. The Heather is an unstructured, modern blazer. This comfortable and stylish jacket has a slightly oversized fit and can be worn in all seasons. It is the perfect editorial layering piece. This pattern is designed to be approachable for the beginner sewist. If you have always wanted to dip your toe into making outerwear but have felt intimidated, this is a great place to start.

The Heather Blazer is fully lined and features a two-piece sleeve, single button closure, front patch pockets and lapel collar. Note the trousers pictured with the blazer are the Chandler Trousers from Untitled Thoughts. Sew both to make a suit!

Suggested fabrics: 

MAIN FABRIC: Any woven fabric with a bit of weight to it is great. Linen, suiting, twill, denim, canvas. Avoid fabrics that can’t take a press since there is a fair amount of fusible interfacing involved in this project.

LINING FABRIC: Typically you want to line your jacket with something that will easily slide on and off over other fabrics. Anything a little bit slippery would work. Rayon, silk, a cotton with a tight weave.

WOVEN INTERFACING: You want the type that looks like fabric (not the papery kind) and is fusible. The papery kind will work in a pinch but it is worth investing in the woven stuff as it will really give your blazer a nicer feel.

KNIT INTERFACING: This interfacing also looks like fabric but has stretch. It will reinforce the collar and lapel without making them too stiff!

Fabric requirements: You may need to purchase extra fabric if your fabric has a heavy nap, is directional, striped, or has an obvious repeat.

MAIN FABRIC: 45″ (114 cm) wide fabric: 2.4 – 3.6 yd (2.2 – 3.3 m) // 54″-60″ (137-162 cm) wide fabric: 1.9 – 3.1 yd (1.7 – 2.8 m).

LINING FABRIC: 45″ (114 cm) wide fabric: 1.8 – 3 yd (1.6 – 2.7 m) // 54″-60″ (137-162 cm) wide fabric: 1.6 – 2.4 yd (1.5 – 2.2 m).

WOVEN INTERFACING: 45″ (114 cm) wide fabric: 0.9 – 1.4 yd (0.8 – 1.3 m).

KNIT INTERFACING: 45″ (114 cm) wide fabric: 0.9 – 1.1 yd (0.8 – 1 m).

Sizing: XS – 7X (approx. UK 6 – 34). Please check the size chart and finished garment measurements.

The Heather Blazer has a slightly oversized fit. Its simple silhouette is designed to give it a modern look while also being easy to sew.

The plus sizes (1X-7X) are designed off of a block with a C/D cup size.

Notions: One 3/4″-1″ button; matching thread; hand sewing needle.
