Turn a flat sheet into something functional and fun—here’s how to fold a sleek rectangular storage box that’s perfect for keeping your desk or drawer organized! Start with a square paper, fold it in half both ways, and unfold. Bring the bottom corners up, flip over, and fold both sides to meet in the center. Unfold the top flaps and press in to make diagonal creases, then fold the side up. Now fold down two corners and open the flap to form a 3D box. #origami #papercraft #paperart #DIY | Paper C
