Opal is the mid-season jacket you slip on without thinking… yet it always makes a little impression
With its structured straight cut, it wonderfully replaces the biker jacket or trench coat for cool summer evenings or spring mornings.
Two versions are offered:
• with cuffed sleeves and a buttoned tab
• or sleeveless, with a cap sleeve that adds character to the silhouette.
You can wear it open, buttoned (6 buttons), or belted, thanks to a system of eyelets at the waist to thread a cord through.
Between its printed flap pockets, double topstitching, and well-thought-out seams, Opal ticks all the boxes of a pattern as pleasant to sew as to wear.
By sewing Opal, you will learn to:
Make flat-felled seams
Sew a button placket
Sew a sleeve cuff
Sew patch pockets with flaps
Opal is a jacket with a bit of ease.
Use your bust measurement to choose your size.
Take the closest size. If your hip measurement is more than 2 sizes larger than your bust, it is better to grade between the two sizes from bust to hips.

The choice of fabric for the Opal jacket will influence both its style and its hold. Materials with structure will highlight the seams and the straight cut of the model, while softer fabrics will offer a more relaxed look.
For a summer or mid-season version, favor cotton canvases, light denim, washed linen, or fine gabardines, perfect for a lightweight jacket with good shape.
For a bolder or sporty look, Opal can also be sewn in technical fabrics such as water-repellent canvas, waterproof gabardine, or even a fine wadding like a light padded jacket.
The key is to use a medium-weight fabric, not too thick, to fully enjoy the model’s neat finishes.

Opal is an intermediate-level model; the finishes are neat and require precision, but nothing unattainable. The various diagrams found in the booklet as well as the video tutorial available on the YouTube channel
