From The Literary Hub:
In designing a book cover, the how is more important than the what. The way something is visually rendered—in the form of typography, image, shape, pattern, color, etc.— is more important than what it symbolically represents. While content and meaning are obviously valuable, they come second to emotion and execution. First, the book has to be picked up. If the design does not get you there, the fact that the cover may perfectly encapsulate the text is irrelevant. It’s what the cover feels like that matters.
This is especially true for contemporary fiction, where more often than not a jacket simply needs to look big, important, and “warm”—this last term being a catch-all for “approachable,” “human,” and “covetable.” Something that is “warm” feels good and real. Conceptually straightforward, this can be tricky to achieve.
. . . .
The problem is always how to start.
So instead of waiting until the end of a design process I can’t begin to add this feeling of reality, I use a physical process to initiate and influence my design. Rather than seek out a library of visual references to copy and modify (endlessly and helplessly scrolling through Pinterest), I look through the manuscript to find material and procedural references. On the most basic level, this means if the book is about water, I play with water.
. . . .
Physically experimenting makes me feel productive, even if nothing immediately comes of it. I can either stare anxiously at a blank computer screen, or I can assign myself a task. Given the choice, I’d rather spend a day carving type out of a block of foam, ripping up paper, or playing with layers of transparency on a light box.
Sometimes the process is successful. Sometimes it’s not. But if I physically make something, I can look at it from different angles, pinch it, twist it, crumple it up. Occasionally this will produce unexpected and exciting results. I’ll end up with a design I did not plan for.

Somehow, PG believes not all cover designers work in this way.
