Custom Interior Sketches for Clients: My 3 Case Studies in Procreate

This September, I want to talk about something very practical and exciting: how to turn your sketches into real commissions.

Procreate is an amazing tool not only for practice, but also for professional client work. Over the past few years, I’ve created a number of commissioned sketches entirely in Procreate: from concept drawings to interior design proposals.

In this post, I’d love to share three case studies with you. For each project, I’ll show the line version and the colored version, and explain how the sketches evolved into final results for clients.


Case Study 1:

Sketch for a Designer Show House (Dallas, TX)

This commission came from a U.S. client preparing for a Designer Show House. Their request was very specific: “We need the rendering of our room to be more suggestive and less detailed.”

By the time I joined the project, the client already had a fully developed concept package:

  • a detailed PDF with the floor plan, furniture layout, and action zones,

  • a separate PDF with material selections,

  • all furniture and textiles carefully chosen.

My task was not to design, but to translate all this information into a suggestive sketch, one that communicates the atmosphere without overwhelming detail. As always, I began with a line sketch to establish composition and proportions.

Interestingly, this project was also the first time I experimented with coloring in Midjourney. Of course, the final colored version will be fully created by me in Procreate, but I thought you might find it interesting to see some of my Midjourney experiments along the way: watch on my YouTube (3 minute tutorial)

The colored version of this sketch will remain under embargo until October 24th. If you’d like to see the full result once it’s released, make sure you’re subscribed to my newsletter, that’s where I’ll share it first.

Case Study 2:

Police Administrative Building Concept (Florida)

The second commission was for a future administrative building of a police station. Since the architecture was still conceptual, the client needed a sketch that would suggest possible solutions.

Here again, I started with a line drawing. Because the building wasn’t yet constructed, we went through several iterations to adjust forms and space. I worked closely with the lead architect, we even had Zoom calls to refine ideas together.

The final colored version provided a clear and expressive visualization of the concept, supporting the architectural vision while keeping the design flexible for further development.

Case Study 3:

Interior Redesign (Los Angeles)

The third project was especially exciting because I was both the interior designer and the sketch artist.

A client from Los Angeles wanted to completely redecorate their existing interior. I developed a proposal and presented it through sketches in Procreate. The process began with a precise line drawing, followed by a colored version that communicated the atmosphere of the redesigned space.

The client loved the result, and this project actually became a bonus lesson inside my Interior Sketching in Procreate Online Course, where I walk you through the entire process step by step.

Final Thoughts

Each of these projects demonstrates how powerful Procreate can be for professional sketch commissions. Starting with a line sketch and then moving into a colored visualization not only helps structure the creative process, but also gives clients clarity and confidence in the design.
