Learn CLO3D in 12 Weeks
Go from complete beginner to confident 3D designer—and transform how you create garments forever.
What if you could perfect fit before cutting fabric, design for your own exact body measurements, and unlock new creative and professional opportunities?
That’s exactly what you’ll learn in this comprehensive 12-week CLO3D course taught by patternmaker and fashion professor Ruby Gertz.
NEXT COHORT LAUNCHES JUNE 2026
Who this is for:
🧵 Hobby sewists tired of ill-fitting garments and wasted fabric
✂️ Indie patternmakers ready to offer custom-fit design services
💼 Aspiring fashion professionals building portfolio-ready work
👗 Current designers looking to level up their workflow and reduce waste
What Makes This Course Different
Most CLO3D courses walk you through rote exercises on default avatars and teach you to make pretty renders.
✨ You’ll learn CLO3D through a size-inclusive, custom-fit lens that emphasizes practical, real-world applications:
✨ Design for YOUR body – In the first few weeks, you’ll receive a complimentary custom body scan that’s ready to use in CLO3D (a $200+ value)
✨ Practical workflows – Learn to digitize existing paper patterns, import patterns from Adobe Illustrator, and export print-ready patterns you can actually sew
✨ Creative, non-standard patternmaking – We’ll explore fit for all bodies, not just industry-standard sizing
✨ Beyond rendering – Yes, you’ll learn to make beautiful images, but more importantly, you’ll learn to use CLO as a practical design and production tool
This isn’t about following along with someone else’s projects. This is about building skills you can apply to YOUR work immediately.
Why CLO3D?
I’m not exaggerating when I tell you that CLO3D has completely transformed my creative workflow.
After integrating this program into my freelance patternmaking and design work over the past two years—and completing intensive training at CLO3D’s NYC headquarters—I can confidently say this is the future of fashion design.
Here’s what CLO3D lets you do:
1. Perfect fit on ANY body.
Use body scans or custom avatars to design garments on someone’s exact shape and proportions. No more guessing. No more “I hope this fits.” You SEE the fit in realistic 3D before you ever pick up scissors. This is game-changing if you struggle to find patterns that fit your body, do custom work for clients with diverse body types, want to design adaptive or inclusive fashion, or are tired of making muslin after muslin.
2. Save time, money, and materials.
I used to spend hundreds of dollars and days of time making physical samples that would ultimately end up in my scrap bin. Now I perfect everything digitally first. I only cut fabric when I know it’s going to work. My fabric waste has dropped dramatically. My turnaround time is faster. My stress level? Way lower.
3. Create portfolio work that gets you NOTICED.
When I pitch to clients or apply for opportunities, I’m not showing flat sketches or photos of samples on a dress form. I’m presenting photorealistic 3D garments that look like they came from a major brand’s lookbook. It completely changed how people perceive my work—and my rates.
4. Open doors to remote freelance opportunities.
Fashion brands—from indie labels to major corporations—are actively seeking CLO3D skills for both full-time positions and freelance projects. These are in-demand capabilities that open doors to flexible, remote work opportunities you can do from anywhere.
Even if you’re not looking for traditional employment, adding CLO3D to your skillset makes you more valuable as a freelancer, consultant, or collaborator. One client project using these skills could easily pay for the entire course.

A note on value:
The regular price of $1495 is roughly equivalent to one college credit at the private university where I teach. As someone who teaches fashion at the college level, I can tell you that this course is comparable in depth and rigor to a 2 or 3-credit college course—but with way more personalized support, live office hours, and a community you’d never get in a university lecture hall.
You’re essentially getting college-level instruction at a fraction of the cost, plus:
• A $200+ custom body scan included
• The ability to learn on your own schedule
• Lifetime access to course materials
• Direct access to your instructor (that’s me!)
Pay in installments with BNPL—space payments out over up to 6 months if you choose.
Why Learn from Me?
I’m Ruby—a patternmaker, designer, and educator based in Philadelphia. I run Slow Fashion Academy, my own studio where I offer sewing and patternmaking classes and do freelance custom design work for individuals and emerging small brands. I also teach fashion design at the college level, where I focus on sustainable and inclusive fashion design.
Over the past year and a half, I’ve integrated CLO3D into my freelance design work and completed a formal training at CLO3D’s NYC headquarters. I’ve seen firsthand how this program transforms creative workflows—not just in theory, but in my actual day-to-day work with clients.
My teaching style is hands-on, collaborative, and focused on real-world applications. I know what it’s like to learn complex software, to feel overwhelmed by the learning curve, and to finally have that “aha!” moment when everything clicks. I’ll be with you every step of the way.
FAQs
When does the course start?
The next cohort will launch in June 2026. Early bird registration for this cohort will open in April 2026. Be sure to subscribe to the waitlist for announcements!
Do I need design or patternmaking experience to take this course?
No! This course starts from the ground up. If you’ve never used CLO3D before, you’re in the right place. That said, I do recommend having some basic sewing experience and having sewn from a pattern at least once or twice before taking this course.
Is this a live course or self-paced?
It’s a hybrid! Video modules are pre-recorded so you can watch on your own schedule, but we have weekly live office hours for real-time support and community connection (these will also be recorded for those who can’t attend live). Modules are released weekly to keep the group moving together.
What equipment do I need?
You’ll need a computer that meets CLO3D’s system requirements and a CLO3D license. CLO offers a 2-week free trial, followed by a $50/month subscription fee. The CLO3D software is not provided with this class, you’ll need to purchase it on your own.
Hardware/desk setup: you’ll want a 3-button mouse with a scroll wheel, and, while not required, a second monitor may be helpful so that you can follow along with the tutorials on a separate screen instead of switching back and forth between windows.
When will the live office hours take place?
Live office hours will be held at the same time every week: our current cohort meets on Tuesdays at 7pm EST. I’ve chosen this consistent schedule so you can plan ahead and block the time on your calendar for all 12 weeks.
If this time doesn’t work for your schedule or time zone, don’t worry—all sessions will be recorded and available within 24 hours. Many students find the recordings just as valuable since you can watch at your own pace and skip to the parts most relevant to you.
How much time should I set aside for this course?
Plan to set aside ~3-4 hours per week to watch the pre-recorded content and complete the practice exercises. You can always choose to forego some of the practice exercises and revisit them later.
What if I fall behind?
Life happens! You’ll continue to have access to all course materials after the 12 weeks, so you can catch up at your own pace. The weekly office hours are only live during the 12-week period, but recordings will be available.
How do I know if this course is right for me?
I want you to feel confident in your decision to join, which is why I encourage you to:
• Watch this free YouTube tutorial to see my teaching style and get a peek at how I use CLO3D
• Email me with any questions before registering
• Review the full curriculum and course details carefully
This course is a significant investment, and I want to help you be sure it’s the right fit for you before you commit. Once you’re in, I’ll support your learning journey every step of the way.
How does the body scan work?
All students will receive an email link to complete a body scan via smartphone before the first live call. I will then be distributing the scans back to students as I receive them.
You can learn more about the body scan process on the TruetoForm website.
What is your refund policy?
All sales are final.
Because this is a live cohort-based course with limited enrollment, personalized support, and custom resources prepared for each participant (including your body scan file), I’m unable to offer refunds once registration is complete.
Do you offer payment plans?
You can divide the total payment over up to six months using Klarna, Afterpay, or Affirm at checkout. Choose the plan that works best for you when registering.
