A course by Flor Tregnaghi, Textile Designer

Learn to design professional patterns in a digital format that you'll be able to print at home
The textile designer Flor Tregnaghi found in pattern making the perfect combination of her two passions: art and mathematics. In this online course, she'll teach you how to put a three-dimensional shape on paper, then bring it to life as you sew.
Throughout the units, you will acquire the necessary knowledge to create garment and accessory patterns in Adobe Illustrator to later print them on a home printer. At the end of this course, you will know how to trace the pattern of a blouse from scratch directly with the computer.

What's included in this course?
You will begin by getting to know your teacher Flor Tregnaghi better and her professional career in textile design, as well as her two projects; Coseacanal and Paulatim. He will also tell you about his influences and what inspires him to continue creating day by day.
Next, Flor will teach you how to fine-tune Adobe Illustrator. You'll see how to create a document, understand layers and artboards, and use basic functions for drawing segments.
Later, you will learn how to transfer the patterns you have on paper to the computer and how to take your own measurements. At this point, you will delve into the logic of pattern making, that is, what you need to know to think in three dimensions.
Now yes, let's get to work! You will draw a rectangle with the measurements and you will create the darts and the flap of your blouse. Then, you will define the design of your garment by drawing the pockets, buttons and hems.
Then, you will apply the seam allowance and write down the information of each piece before doing the quartering and creating the "marked". This way you will know how to position the pieces on the fabric and how much fabric you will need.
Finally, your teacher will explain how to separate the pattern into different sheets to be able to print it on a home printer in A4 size, and she will tell you her trick to join them easily and create a giant paper pattern.

Flor Tregnaghi
A course by Flor Tregnaghi
Flor Tregnaghi's family had a fabric store in Argentina, which is why she was born among patchwork and learned to sew even before writing. He was a finalist in the “Getxo moda” contest for future promises from the world of fashion, and won a scholarship to study at Central Saint Martins for the Biaaf international contest. After working with a friend on a project called Cosecanal, she is now embarking on her own creative workshop: Paulatim.
Paulatim is her personal creative workshop, where she designs garments, advises on pattern making and teaches sewing to anyone who wants to create their own clothes and take care of their garments by giving them a new life. It is a meeting space, but also for environmental awareness. In addition, Flor is an illustrator and pattern maker for Patrones magazine.

FAQs
Digital pattern making involves creating garment patterns using digital tools like Adobe Illustrator, allowing for precision, quick edits, and exporting for printing or fabric cutting.
This is an intermediate-level course, so it’s recommended to have basic sewing skills and some experience with Illustrator before starting.
You’ll need a computer with Adobe Illustrator installed, access to a home printer, a measuring tape, paper, scissors, and optionally a scanner or camera to digitize patterns.
You’ll learn how to create digital patterns from scratch, digitize hand-drawn patterns, add seam allowances, prepare files for printing, organize layers, and apply creative and sustainable fashion techniques.
The process starts by setting up the document, drawing the base rectangle, taking measurements, adding darts, sketching the flap, and applying seam allowances—all using Illustrator’s tools.
Yes, the course teaches how to split digital patterns into A4 pages, print them at home, and assemble them correctly to get a full pattern ready for cutting.
In Illustrator, you select the piece and create an extra outline about 1 to 1.5 cm around the original pattern to leave enough room for sewing.



I am new to Adobe Illustrator and this class is beginner-friendy. The pacing is right for me to follow along. I am still on Unit 2 but I am really enjoying it as i familiarize myself with the tool.
