Jasika Blazer Pattern
The Jasika Blazer is a classic tailored jacket with a semi-fitted shape that will never go out of style.

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.

Fast and quick shipping. I haven't made the Blazer yet, I purchased the pattern for a project in January.
Easy to download. Instructions great! Better then regular patterns from Vogue or Burda..
Love this pattern, it will be my go to pattern for a jacket from now on, I made a muslin to start just in case I needed to make any alterations, not a one, the instructions are very clear, and easy to follow, the next project will be making the cutting table, even went so far as to order the hardware during Covid 19 and everything arrived in New Zealand within 6 weeks. Pictures to follow. Keep up the excellent work, your a treasure.
The pattern is great, instructions clear and the blazer is beautiful. The tutorial was wonderful and perfect for me. Heather is so clear and upbeat and made this challenging garment seem easy to sew. I haven’t seen in years and still can’t believe I made a beautiful, professional looking blazer. Couldn’t have done it without Heather’s guidance!
This is a very well drafted pattern and the directions are excellent. The video is also excellent...she moves along at a good pace; there isn’t any wasted time. I do a lot of couture sewing, but the blazer lapel always seemed confusing. I have done hand sewing in the critical areas and am pleased with the result. Sleeves go in tomorrow ...more hand sewing. This has been a good learning experience.
