Picture Frame 3.0

Building on previous versions, this design introduces a sloped inner frame, creating a more refined and architectural look. The structure is significantly more complex than before, but the result is strong, clean, and visually elegant — while staying true to sustainable principles.
This project explores how far cardboard can go when we fully understand its structure and use it intentionally.

Lampshade

A modern cube-style lampshade using L-shaped frame pieces. Designed for ambient lighting, this lightweight and stylish piece is perfect for home decor projects using sustainable materials.
*For this project, I used a Baby Night Lamp (LED).
Cardboard is a flammable material, so using incandescent bulbs or other heat-generating lights can be dangerous. Please make sure to use a low-heat LED light only.

Tea Box

A clean and practical Tea Box using 4mm thick upcycled cardboard. It features a transparent lid for quick visibility, an optional magnetic closure, and dividers that fit standard tea bags perfectly. This is a beginner-friendly but rewarding project—ideal for crafters who enjoy both form and function.

Christmas Village

Cozy little houses for your Christmas village — all using upcycled cardboard. These designs are perfect for holiday decorations or as unique mini gift boxes to surprise your loved ones.

Cube Frame

📦 Think cardboard is just for boxes?
In this tutorial, we’ll show you how to turn corrugated cardboard into solid, clean-edged cube frames—perfect for decorations, educational projects, or modular designs.

This project is all about understanding the structure of cardboard and designing in a way that brings out its full potential. No extra materials needed—just smart cutting, folding, and layering.

Book-shaped Box

Upcycle cardboard into a book-shaped gift box with a seamless hinge. *This template isn’t included paper marche part as shown in the video.

HAKOZEN Box & Tray

Do you know Hako-Zen?

It’s a traditional Japanese item from the Edo period to the early Showa era (approximately 1603–1950).
Each person had their own personal set of dishes, stored in a box that also served as a tray and a mini table.
Because people traditionally sat on the floor, this box fulfilled the role of a table in daily life.

Inspired by the smart functionality of Hako-Zen, I’ve reimagined it for modern use—
as a multi-purpose organizer for art supplies, tools, or everyday items.
Give it a try and customize it to suit your lifestyle.

Picture Frame 2.0

A technique called(I named it:)) the “sandwich.” I’m applying a method I’ve previously used for the middle tier of a jewelry box, a lidded box made by weaving paper, and the accessory tray in a desktop organizer. This technique lets you sandwich the front cover and the card, and the back can be opened without glue, making it easily accessible!

Collection Box

HIGHLIGHTS
• Built-in magnets create a satisfying “pat” sound when closed.
• A plastic film window lets you see inside the box!
• Customizable interior: Use it as a collection box (4×4, 3×3, etc.), a display box, photo frame, shadow box, or anything you can imagine!
