I Made a Tambour Door from ONE Piece of Cardboard

A seamless tambour door — made from a single sheet of cardboard. Look closely at cardboard and you'll find a hidden structure: a wavy corrugated layer sandwiched between two flat sheets. By studying that structure, I developed a technique called the "half-cut" — where only one layer is cut away, leaving the rest intact. No extra materials, no patching. Just clean, seamless corners. Repeat that cut 32 times, and you get a fully flexible tambour door that slides open and shut like silk. The curved slide rail guides it around the arc — cut with the precision of a sewing machine. This is a new way to work with cardboard. I hope you'll give it a try. 📐 Template A4 Printable 1/2 Scale PDF Template is available on: https://itoshige.com/for-makers/desig... #CardboardDIY #TambourDoor #Upcycling #CardboardFurniture #DIYCabinet 📍 Chapters 00:00 Intro 00:55 TItle 00:59 Highlights 00:00 Dimensions, Materials, Tools 01:54 Part 1 Tambour Door 09:33 Part 2 Side Part 18:14 Part 3 Bottom Part 19:19 Part 4 Top Part 20:53 Part 5 Back Part 22:34 Part 6 Fix Door 24:20 Part 7 Assembly 28:59 Result 29:38 Introducing a Template Book 📏 Project Specs Finished Size: H200mm x W200mm x D150mm Material: 6.5mm thick cardboard Amount of cardboard: Approx. 850mm × 550mm Estimated Work Time: Approx. 4-5 hours with template Skill Level: Advanced ★★★ 📘 Get My Template Book on Amazon Make 20+ cardboard furniture & storage projects with ready-to-use patterns: • [EN] “CARDBOARD DIY by ITOSHIGE STUDIO” https://www.amazon.com/dp/8409713438 • [ES] “Artesanía en cartón por ITOSHIGE STUDIO” https://www.amazon.com/dp/8409713748 • [JP] ダンボールで作るミニ家具&収納 (Kindle版) https://amzn.asia/d/aQE7k3U 🛠️ Tool List *As an Amazon Associate, I earn from qualifying purchases.
