Learn Cartonnage From Scratch:
No Kits, Just Skill and Freedom.
1, 2, TRAYS!
In this online cartonnage course, you’ll learn how to design, cut, and assemble a complete 3-piece desk organizer — transforming plain cardboard into a beautiful, handmade set — through the Handmade Precision Cutting method, a clear, step-by-step process for cutting accurately by hand.
No pre-cut kits—just your hands, simple tools, and the joy of seeing your work come together piece by piece.
Design & Plan
Learn how to think like a designer — understanding proportions, structure, and how to plan your own projects.
Cut Precisely
Discover the Handmade Precision Cutting method, a smart, easy-to-learn system for cutting thick boards by hand with accuracy. You’ll see how to measure, align, and cut confidently — so every piece fits perfectly.
Assemble & Cover
Glue, fold, and finish your trays using fabric. You’ll learn every step, from structure to finishing details.
Create with Confidence
Once you master this process, you’ll have the freedom to design and build any cartonnage project — boxes, organizers, covers, and more.
WHAT IS CARTONNAGE?
A timeless craft, reimagined for today’s makers.
Cartonnage is the art of building functional and decorative objects using cardboard, fabric, and paper.
Each piece is designed, cut, and assembled by hand — a blend of precision and creativity that turns simple materials into lasting, beautiful pieces.

Feel surprisingly rewarded by what you can accomplish with simple tools and materials!
