Picture Frame 3.0 – Beveled Edge Design with Corrugated Cardboard #upcycling #pictureframing

In this video, I’ll show you how to make a Picture Frame 3.0 entirely from upcycled cardboard. 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. 📐 Template A4 Printable 1/2 Scale PDF Template is available on: https://itoshige.com/for-makers/desig...
