The Sketch MasterclassÂ
Not quite ready to dive into the full Foundations course? Start here.
The Sketch Masterclass is your go-to for learning how to sketch with a penâspecifically for interior design. Itâs the first skill youâll need before jumping into the full hand-rendering process.
We pulled this section straight from our Foundations course, a small section of Module 1 to be exact, so you can focus on just one thing: sketching. Once youâve got that down, youâll be prepped and ready for the full deep-dive into drafting, drawing, and rendering inside our Foundations course.
Start slow, build your confidence, and take it at your own pace. This course is fully on-demand and ready when you are.

Hi, I'm
Shannin Williams
Interior Designer & architectural Illustrator
I help interior designers break free from digital constraints and reconnect with their authentic creative roots. Through essential hand skills, I empower designers to craft stunning architectural illustrations entirely by hand, infusing authenticity and artistry back into their projects.
This allows them to sketch, draft, draw, and hand-render every element of their designsâkeeping the work true to their vision, all in-house. The result? Joyful, meaningful creations that delight clients, elevate their design business, and drive increased revenue.
