How to Draw and Paint Cloth Folds from Imagination

Hey everyone,

I've been sharing tips on how to study fabric and how to render cloth but not on how to approach shapes in cloth folds from imagination. Props to one patron named 'Pod' for dropping this question in our Discord channel.

When I imagine and create cloth folds, I often use different strategies depending on how the cloth is being bent. Today, I want to share one of them. I usually start by sketching lines that converge at the point where the fabric touches an object. This touchpoint is where the fabric's reaction begins. From there, I create triangular shapes using these converging lines as a guide. The triangles represent the folds, emanating outward from the point of contact.

Here's how it goes with a reference:

1. I first draw the shape on which the fabric will rest or the shape that will change the fabric fold. For instance, if it’s clothing, I briefly sketch the character's body, not only to get the proportions right but also to see which parts of the character's body will touch the fabric, creating folds. Depending on the material, you will see more or fewer folds.
2. I imagine lines coming out of that touch point, as if it were a perspective point.
3. From those lines, I define triangles and assign values depending on the position of the lights.
4. As for how to move from that point to a more sophisticated render, check the how to render cloth previosuly mentioned on this article.

Conclusion

In simple words, find out what form is actually causing the fold's shape, create triangles from that point, and choose to position shadows inside those triangles depending on your source of light. Now, like I said, some fabrics do not create the same amount of folds or triangular shapes; some produce fewer straight lines based on characteristics like their size. But that’s a good reason to practice from real-world references. By identifying how certain folds behave, you will be able to accurately reproduce them from memory once you know the characteristics of the fabric you plan to depict.

Tomorrow, I'll be sharing the process video of this piece along with the files and insights. They will be available for Mastering Maestro tier and above. Feel free to upgrade if you want more insights about my work.
