Pattern Hacks & Inspiration
From the Closet Core Patterns Community
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.
Please see my review on pattern review.com:
Easy to understand and follow. Challenging techniques. Im learning a lot.
I love this pattern, the fit is perfect for me with very few adjustments. The written instructions are clear and easy to follow but I also had the tutorial to follow which was very helpful. I can't believe I made a blazer, it looks amazing and fits great! I'm already planning my next blazer project.
Nice pattern, instructions and online video. Haven’t made it yet....hope to get to it soon.
