Stand Out from Other Designers

Match Your Visuals to your VisionÂ

Lead your Brand with Creativity
YOU HAVE GREAT IDEAS BUT NO ONE EVER TAUGHTÂ YOU HOW TO SHOW THEM.
NOT with MARKERS. NOT with A COMPUTER.
AND THAT'S the GAP KEEPING YOUR WORK from STANDING OUT.
You buy the markers, sit down to try—and end up disappointed because no one ever taught you how to actually use them.
You search YouTube, hoping for help, but it’s all noise and no answers. So you turn to computer renderings, but the programs feel clunky and frustrating, and your work ends up looking worse—not better.
Hiring someone to do it for you? That’s expensive.
So in the end, you skip renderings altogether.
Your presentations are missing the one thing that could seal the deal: a visual that actually looks good.
Your clients hesitate, ask for changes, or don’t fully buy in—because they just can’t see what you’re trying to say.
And when that happens, it’s your confidence that takes the hit.
Â
STAND OUT FROM OTHER DESIGNERS
MOST INTERIOR DESIGNERS RELY on THE SAME SOFTWARE and DIGITALÂ TOOLS, WHICH MEANS their PRESENTATIONS ALL START to LOOK the SAME.
But when you learn to render by hand, your visuals instantly stand out—because no one else is showing work like yours.
It’s not just different, it’s memorable. And that’s what makes clients pay attention.

MATCH YOUR VISUALS TO YOUR VISIONÂ
YOUÂ Â KNOW WHAT YOU WANT the SPACE to FEEL LIKE, BUT the VISUALS YOU CREATE DON'T QUITE GET THERE.
Whether it's a clunky rendering or a inspiration board that falls flat, your ideas get lost in translation.
When you learn to hand render, you’re able to match your visuals to your actual vision—tone, texture, mood, and all.
Clients don’t just hear your ideas—they see them.

LEAD YOUR BRAND WITH CREATIVITY
YOU WANT your BRAND to REFLECT YOUR CREATIVITY, BUT WHEN YOUR VISUALS DON'T LOOK POLISHED or PERSONAL, it's HARD TO STAND OUT.
Â
Hand rendering gives you a way to express your ideas with clarity and character—no templates, no shortcuts.
It puts your creativity front and center, so your brand feels as custom and thoughtful as the designs you create.
The key is you MUST learn how to create them properly so they will look great and your clients will trust and understand them.
If they are sloppy, clients won't buy-in.

I UNDERSTAND—BECAUSE I WAS IN THE SAME PLACE.
I WAS STRUGGLING TO PRESENT MY DESIGN IDEAS CLEARLY, TOO.
IN MY OWN INTERIOR DESIGN BUSINESS, COMPUTER RENDERINGS just weren't CUTTING IT. NO MATTER HOW HARD I TRIED, they NEVER SHOWED what I NEEDED THEM TO SHOW, PLUS they WEREN'T ON BRAND FOR ME.
That’s when I turned to hand rendering—not because it was trendy, but because it's what I knew, it's what I learned in design school along side of computer aided design programs. I was desperate to show my actual design ideas as they were going to be in the end as I envisioned them—not just what the computer could do.Â
I knew I needed to refine my hand rendering skills from design school and so I did! I practiced daily and used it in my work, presented to clients and formed marker strokes and techniques that made my work stand out from anything a computer could do.
Now I'm eager to teach you!
EARNINGÂ BOTH a BACHELORSÂ and MASTERS DEGREEÂ in INTERIOR DESIGN and ART
My background is rooted in real design education along with intensive training in hand skills before computers took over the industry. These techniques became second nature to me, and I used them daily in my own design practice to create work that was clear, compelling, and client-ready.
HAVING TAUGHT HUNDREDS of INTERIOR DESIGNERS ACROSS the INDUSTRY the SKILL OF HAND RENDERING
Over the last two decades, I’ve taught hundreds of interior designers across the industry how to hand render—many of whom had never picked up a marker before. With the right tools and guidance, they’ve learned to render with confidence, reconnect with their creativity, and use hand-drawn visuals to sell their work faster.

HI, I'M SHANNIN
I’m passionate about teaching hand skills, and I’d love to help you learn them too.
Over the years, I’ve developed my own techniques, along with tips and tricks you won’t find anywhere else—not even in design school.Â
That’s why I started The Bertrand Williams School of Design Visualization—to help interior designers like you gain these skills and become the confident, accomplished professionals you’ve always wanted to be.
That’s exactly what the workshops are for—to give you hands-on, step-by-step guidance. I’ll be right there beside you, ensuring you get the best possible education in learning these skills. This is my ultimate goal for you, and it’s why I offer the courses and workshops the way I do. We hope you’ll join us!
