Ready to think like a patternmaker?

Confident Patternmaking & Confident Grading are 90-day courses that teach you everything you need to know to draft and grade professional-quality sewing patterns for any garment you can dream.

Does this sound familiar?

✄ You're struggling to piece together patternmaking knowledge from books and mini-courses and you wish you could find everything you need to know in one place.

✄ You've tried to learn patternmaking from the traditional fashion world but have found it dismissive and avoidant of fitting clothes on bodies that aren't straight, small sizes.

✄ You're not in a place where you can drop everything to go back to school to learn patternmaking.

✄ You can't find good information on how to grade patterns for a wide size-range, let alone how to grade them properly in the first place.

✄ Fitting and adjusting patterns feels like a mystery and requires consulting books and polling others who give you conflicting advice.

✄ You have a dream of starting your own brand or sewing pattern business but you haven't found anyone to teach you what you need to make it happen.

✄ You are READY to trade "trial and error" for a clear roadmap to making the sewing patterns you dream of.

You're in the right place!

What students have to say 💬


Enrollment opens soon for the cohort starting January 2024.

Plan to dedicate about 3-5 hours per week, but just like anything in life, the more time and energy you dedicate, the faster you’ll see results. 

These programs condense what you would learn in a multi-year patternmaking degree program into just 90 days.

They also cover material that few to no other patternmaking courses offer, such as size-inclusive patternmaking and grading and techniques for working digitally in Adobe Illustrator.

You can DM Victoria on Instagram @erbaccia_studio!

Teaching the course directly in Adobe Illustrator has many advantages over learning first on paper:

– No need for a large, well-lit work surface. All you need is a computer.

– Working digitally offers a precision that can be challenging to achieve on paper (especially when creating large shapes or creating precisely square and parallel lines.

– It’s faster. Copying is instant (as opposed to time-consuming hand tracing) and modifications happen so fast that you’ll feel more free to play and experiment.

– It’s the only software you need to package your patterns for sale as PDF downloads, should you choose to do so.



We’ll use predominately metric measurements throughout the course, but you’ll be fully supported and resourced for using Imperial measurements in your own work if you so choose.

Hi! I'm Victoria,
your teacher!

I studied patternmaking and tailoring at Istituto di Moda Burgo, one of the the top fashion schools in Italy.

I’ve been working as a patternmaker for Violette Field Threads since the very day I graduated, and I founded my own sewing pattern brand Erbaccia Pattern Studio.

Before I went back to school to learn patternmaking, I was an organic farmer in Montana for nearly a decade, where I raised sheep and veggies and taught field-to-fiber Indigo dyeing classes.

The organic farming community I was a part of was always generously sharing knowledge and resources with one another. So, imagine my shock when I went from that world to the competitive, elitist, and exclusive fashion world! I’ve vowed to dedicate myself to mastering patternmaking skills and sharing them widely, generously, and inclusively.

And just between me and you: there’s never been a better time to be a patternmaker. We can work digitally from anywhere in the world, and change peoples’ lives with our designs. The world of inclusive fashion is rapidly growing, and now is the time to learn what you need know and hit the ground running!

Hi, I'm Jess,
your mentor!

I’m a sewing pattern designer, freelance pattern maker and grader, and someone who loves to sew clothes!

In January of 2023, I took a leap of faith and enrolled in Victoria’s pattern making and grading courses. Just 12 weeks later, I launched my very first PDF sewing pattern, the Tapioca Trousers! 

With Victoria’s guidance, I became a full time pattern designer, freelance patternmaker and grader, and a mentor to folks just like you who are starting out on their patternmaking journey.

I’m passionate about making sewing and designing clothes more accessible to anyone who’s interested in learning. Whether you just want to design clothes for yourself or you want to start your own pattern line, you’re in the right place. I truly believe that with hard work and the right guidance, you hold the skills to make all your pattern making dreams come true.

Are you ready?
