No prior knowledge needed, learn from scratch.
Learn the fundamentals you never got round to asking about.
Dip into modules to fill your gaps, from tilings to colour to selling.
Learn about the history of patterns, useful tools to get started, and the foundation of good pattern design.
Next up: the full design process, advanced techniques, creating your own source images, and turning your patterns into a business.
Big topics split into digestible steps.
Easy to fit in your busy schedule.
Start today, pick it up whenever you like.
Short tasks, right where you learn the idea.
Pick a source image with strong contrast (dark darks, light lights) and make a pattern from it. In the Effects tab, switch on Duotone and pick two colors you like. Now change just one of the two.
Watch what happens to the other one: does it look warmer, cooler, duller, brighter than before? You didn't touch it, and yet it changed.
Start with modules 1 to 3 today.
We'll email you the moment a new module unlocks.
No strings attached, come in!
Start free masterclassThe app we built to make pattern design accessible to all: just choose an image, select a section and turn it into a seamless pattern in real time.
We use it during the masterclass to explain pattern concepts and if you wish, you can try it yourself for free while you learn.

Signing up for the masterclass gives you 2 weeks of full access to the Repper app. No credit card needed. When your app trial ends, you keep access to the masterclass forever.
You don't need Repper to follow the masterclass, but it'll help you get more out of it. See the FAQ
We created the pattern app Repper, launched in 2018. We've been teaching about pattern design on our YouTube channel since 2021 to over 5,000 subscribers. This masterclass is everything we've learned in one place.



Not much of one. We've learned most of what we know from the pattern community over the years, and we've been sharing it back through our videos for nearly as long. This masterclass is the next step: everything in one place, in the right order.
We make some income from Repper, which is what lets the masterclass be free. If you enjoy making patterns with our pattern app during your trial, we hope you'll stay on with a Pro membership. If not, the masterclass is still yours, for good.
No. Module 1 and most of module 2 don't depend on any tool, and the ideas in the rest apply whatever you use. From module 3 on, Repper is how we demonstrate things, and your trial gives you full access, so the exercises are easiest with it. A few parts, like exporting, are Repper-specific and come with general advice on things like resolution and DPI.
The masterclass stays yours, all of it, for as long as you like. To keep the full toolset of the Repper app, simply get a Pro membership. Nothing renews or charges by itself, because we never asked for a card.
No. Photos, scans, cut paper and simple shapes all make good source material, and module 2 shows you where to find it and how to make your own. If you do draw, all the better.
Chapters take 5 to 15 minutes, modules about an hour plus exercises. The three modules available now add up to roughly three hours. It's self-paced, so spread it over an evening or a season.
Yes. Anything you make from your own images is yours to sell, through print on demand, as licensed designs, or in your own shop. Be careful with source images you didn't make: their license decides what you can do with them, and we point you to safe sources in module 2.
Both. Beginners get a start that assumes nothing. If you've been making patterns for a while, module 3 and up give you the foundation most of us skipped, and techniques to widen your range.
It was made by humans, for humans. Wouter wrote every chapter and the videos were filmed and edited by Michel. All ideas, opinions, examples and occasional silly jokes are ours. We used AI to assist with fact-checking, formatting and proof-reading.
