The included alteration instructions are very unclear about how and where to make a petite adjustment. Finished garment measurements would also be helpful. I
I had been eyeing off the Jasika Blazer many years before I jumped in and signed up for the online class!! My only regret is waiting so long! Heather explains the steps in a clear and easy to understand manner - while remaining highly encouraging and enthusiastic the whole way! The pattern is drafted beautifully - and the online course is clear and well filmed which makes the entire process so rewarding! I know I will be making another beautiful blazer - after such a successful first toile and then blazer.
This course was brilliant, I’m a fairly novice sewer and felt that every point in the pattern was covered in the lessons so I never felt panicked at any stage.
It’s a very complicated pattern but as it’s broken down into detail I felt confident and I’m very proud of my end result . Going to make one for my daughter now and then do the jeans course !
The class is great. It really helps and I see that you really answer questions. I already asked about the backwaist length....why don't you include it on the pattern?
I ordered the paper pattern and regret it. I can't determine the size of the front neck dart from the big blob of lines....also the paper is too thin. The first thing I had to do was to fuse interfacing to it. I have made traditional jackets before, so this one is introduces new techniques to me. THANKS AND KEEP UP THE GOOD WORK. WHAT IS NEXT?
Superb course. Fully explained and demonstrated. I will feel confident to try my first jacket. Being able to get the relevant notions as well, will make this so much easier. Very happy with this.
I've been sewing for over 25 years so I rarely feel the need for this kind of thing. The Blazer was intimidating though, so I went for it. I'm so glad I did! I watched about half the classes before I started my jacket. I'm through making the fronts, so far so good! I really think I got a lot of confidence and skills from watching the lessons and thinking through the steps ahead of time.

I bought two of the kits thinking I would make the dress (not shirt) and didn't think to look at the sizes and the fabric requirements - I just assumed that the kit would have enough fabric to make the pattern shown in the illustration. Once I read the pattern, I realized that, according to the pattern, I needed more fabric than was offered in either sized kit. I texted with the folks at Closet Core. It turned out for my size, there was enough fabric in the kit, though that is not what the literature would have you understand.
It all worked out and I am pleased with the dress. I did look at Youtube to find out how to make thread belt loops, though.
Love core patterns! Looking forward to sewing with the beautiful fabric too
I wanted a bright tee for high visibility when cycling along roads and on shady rail trails. This color is bright! Fabric is soft and sews up easily - not a lot of curling at the edges like some jerseys. Although it initially felt very drapey, once I had the tee made up it had enough body to skim the body without being clingy. I haven't yet had the chance to wear it to test its moisture-wicking quality.
This IS lovely fabric but, I found it a little tricky to work with. I'm not a beginner; I'd call myself intermediate. I'm rating this four instead of five because after reading so many glowing reviews I decided I had to have this fabric, but I also want to let potential buyers know what to expect. (After working with it I went back and re-read the reviews and discovered many of the reviewers had not actually sewn it up yet.) It is slippery- no problem. I straightened the grain and pinned the fabric to paper to cut out. It wrinkles easily but irons well - with a press cloth and mid temp iron. It has no ease what so ever, so attaching the collar on the shirt I made was tedious. I think if you choose your pattern wisely and you are patient and meticulous you'll be rewarded with a lovely garment. I made the Style Arc Monty shirt but I don't think it was the best pairing; the simpler the pattern the better. I see they recommend the CC Amy jumpsuit which would be a great choice
Sewing is generally a solitary hobby. While I like the solo time, I also like to talk about it, share with people who aren’t going to just smile and nod, and feel connected meaningfully to sewing folks. Crew does this for me through its awesome community forum app and monthly videos with the Closet Core Team. I committed to a year to get a year membership to revive my sewjo. The connection I’m feeling again to sewing is exciting, and that’s even without the great patterns!
