@itoshige_studio: Don't throw away your scrap cardboard — turn it into something useful and beautiful.In this video, I'll show you how to make clean, elegant trays using the sandwich technique — working with three different cardboard thicknesses: 3.5 mm, 4 mm, and 6.5 mm double wall. No large sheets required. Small scraps and leftover pieces are all you need.I also line the inside bottom of each tray with washi paper — a simple touch that makes a big difference in the finish.The sandwich technique has already appeared in seven of my designs, and this is one of the most beginner-friendly ways to try it. 📐 Template A4 Printable 1/2 Scale PDF Template is available on: https://itoshige.com/for-makers/designs/basic-tray-sandwich/ #upcycling #cardboardorganizer #sustainablecreations 📏 Project Specs Finished Size: 3.5mm: H200mm x W90mm x D30mm 4mm: H200mm x W150mm x D40mm 6.5mm: H330mm x W240mm x D40mm Material: 3.5mm thick cardboard: Approx 300mm x 250mm 4mm thick cardboard: Approx 400mm x 350mm 6.5mm thick cardboard: Approx 600mm x 450mm Estimated Work Time: Approx. 1 hour/piece with template Skill Level: Beginner ★☆☆ 📘 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 ⸻ 🧰 How to Work with Corrugated Cardboard Series: • Vol.1: 3 Cutting & Shaping Basics https://youtu.be/uo4NYqQ5Nco • Vol.2: Covering Corrugated Edges (Grooves & Tabs) https://youtu.be/Ur1imZNL56A • Vol.3: 3D Assembly & Construction https://youtu.be/-1RUcCE8RLk 🛠️ Tool List *As an Amazon Associate, I earn from qualifying purchases.
