Geometry in Pattern Making
The Skirt

Concept of Geometric Pattern Making

Geometric pattern making is based on the use of simple shapes —circles, triangles, rectangles— to build garments with mathematical precision and a clear method.
Unlike traditional Cartesian drafting, this system relies on formulas, radii, and proportions, allowing direct design on paper or screen with exact and repeatable results.

In this series of articles, we’ll explore how geometry can become a creative tool in the service of design and garment construction.
Although at first formulas may seem intimidating, there’s no reason to fear them: everything is explained step by step, from the basics to the most useful calculations.
And if any doubt remains, you can always turn to the great encyclopedia of our time: the web.

The Geometric Skirt

The skirt will be the first practical example in this series dedicated to geometric pattern making.
As we publish new videos, we will expand this post into a complete monograph on the circle skirt.
Here you will find the essential formulas, the most useful internal lines, and how to use the gardener’s compass.

01. The Circle Skirt

Learn step by step how to calculate and draw a circle skirt from scratch.
We explain the necessary measurements, the radii and complementary lengths, and how to obtain the exact shape using the gardener’s compass.
Ideal for students, teachers, and pattern-making professionals seeking precision, method, and geometric understanding.

02. The circle skirt made of several pieces

In this video we show how to make a circular skirt composed of several panels, based on what was explained in the previous video.

03. The circular skirt with less flare

From an ancient formula is born a new made-to-measure creation.

A brief look at the geometric origins of patternmaking.
Each body, a pattern. Each pattern, an angle.

In a breath… made to measure.
