I grew up in a suburb of Chicago, and always loved the Chicago brownstone style homes. For this blog post, I decided to do a mini process blog, and share the beginning to end process of making a pattern. I'll keep it brief but if you have any questions please post them in the comments and I'll check back to answer.
First, I always start out with my sketchbook. I'll begin by just jotting down my concept and a few visuals. I then collect reference material. For this particular pattern, I knew I wanted it to be loosely-drawn and simplified, so I wasn't as concerned with details as I was with the overall shape and style of each house.
For this project, I limited my drawing time and used one pen for all the details. Here's a few of the sketches I did before scanning my blackline drawings into the computer to digitize and colorize.
When I begin working with color, I typically do it in Adobe Illustrator. I like to work at a brisk pace so I see results quickly. Part of what I love about Illustrator is how efficiently I can make things happen, and finally get to the point where I play around with pattern and layout. Which is obviously the BEST part. :)
Here are some of my in-progress colorizing:
The final fun step for this piece was to work with textures and paint in Photoshop. I cropped the pattern down to a size I love, and began painting and adding depth and texture to the houses, so no two look the same. The end-use of a pattern sometimes means that I don't do this step - but when I've created it for fun, I can paint to my heart's content. Here is the final brownstone pattern painted, and envisioned as a pair of gift bags.
