Main fabric for woven blazer: Mid- to heavy-weight wovens, such as suiting or tweed, made from wool, linen, or wool blends. Lightweight coating also suitable. Avoid fabrics with a very smooth surface like gabardine, as they will likely shine when pressed.

Main fabric for stretch blazer: Mid- to heavy-weight knit fabric such as stable ponte, or mid-weight stretch wovens such as stretch suiting.

Body lining: If using a non-stretch woven, use a light- weight woven lining such as rayon bemberg or crepe de chine. If using a stretch woven or ponte, use a knit lining for the body, such as ITY or other slick jersey.

Sleeve lining: Light-weight woven lining such as rayon bemberg or or crepe de chine, for both stretch & non-stretch blazers.

Pocket lining: Stable woven such as quilting cotton or shirting.

Interfacing: Mid-weight weft fusible interfacing and mid- weight knit fusible interfacing. Optional: use heavier weight interfacing for pocket welt; fusible horsehair canvas can be used for chest shield interfacing.

Learned a lot from this blazer

Overall really liked making this blazer. I found the instructions well-written, and referenced the photos from the sew-along for one question I had about sewing the hem. I did size down in the bust for this, because i wanted to be able to wear it open without it looking super baggy in the front. I probably should have sized down 2 cup sizes because it's still a TAD baggy when I wear it open - but it fits perfectly when I button it. I learned the bound buttonhole for this jacket and it took me about 4 tries in practice scraps to get it - but it does add a very polished look!

I used silk noil for the main fabric and crepe de chine for the lining, both were easy to work with.

A big project - and worth it

I love this pattern. I made it in navy twill linen, lined with silk from an old sleeping bag liner, and it turned out beautifully. The instructions are clear and thorough. I was looking for a big project, and boy did I get it. There are LOTS of steps. My one suggesion is that psychologically it's tough to start with a bound buttonhole and welt pockets. They're tricky, especially the pockets. I reckon it's better to sew a few big seams first to get into the groove (e.g. start with the sleeves). I will definitely make this pattern again, but I need some recovery time first!

Difficult to

Perfect accomplishment of narrow shoulders (think size 8) to generous bust (think size 14-16). Wonderful

Love the fit!

It's awesome to get a pattern that only needs minor tweaks for an amazing fit (usually it's easier draft up a pattern on my personal block with other designers).

I made the back darts have a little more dart value rather than a sway back adjustment and graded from a 12 shoulders, 14 waist and through to 18 hips

I freestyled mostly but the instructions I did read were nice and clear (even if I still didn't follow them) and you can tell it was drafted with a lot of consideration for getting a quality finish.

Great Blazer Pattern

Awesome pattern! Very few fitting adjustments were required!

Auburn Blazer is great as is - or hacked!

Hi Jenny,
I originally ordered the Auburn Blazer pattern in Dec. 2021 because my niece wanted a denim jacket and this was the closest pattern I could find that was designed for curves (in Cashmerette patterns, she's a 14 c/d in the upper body, a 16 waist and 14 hips). I made a muslin with the regular sleeves which were too tight, so we knew we would use the full bicep sleeves in the final version. I then moved things around and cropped the pattern to the length she wanted. The final version was completed in early March, 2022.

Then in early January, her younger sister asked if I had a black blazer she could use for Model UN, starting 2/3. I proceeded to have her try on the muslin (with the full bicep sleeves) from her sister's which worked perfectly. Tonight she came to pick up the finished blazer.

I have been very impressed with your detailed instructions and illustrations. I love the "tailoring tips" you include for those who either have more experience or want to make use of your added resources to add things like bound buttonholes (when I've made men's jackets using patterns from one of the big companies, I've had to remember on my own to add in the bound buttonholes).
