So this is organizer I made from tetra-pack cartons to store my leather scraps. The box I used as a basis is a box from office paper. The tetra-packs fit in it perfectly in this configuration, but you can use whatever you want. To hold everything together, I used a stapler mainly because I have a fancy one with long reach but a hot glue gun or double-sided tape will do as well. I know that my creation doesn’t look very cute but for me it’s a temporary solution, and you can make it as accurate as you want. And yes this is not the best way to store leather, but I don’t have enough space to keep it flat in a convenient way.
