When I'm working on a project with lots of loose parts, I fold these cute little boxes all the time to keep track of things. Even for an origami novice, these boxes are an easy way to organize your desk space.
Step 1: Folding the Box
Your paper should be roughly rectangular in size before starting.
1. Take two parallel edges and fold them inward, leaving a gap between them. The distance from the edge of the model to the end of the flap will roughly be the height of the box walls (H)
2. Fold the corners in, leaving a small gap between the edge of the newly created triangle and inner edge of the flap.
3. Fold a thin flap from the inner edge, lining the crease up parallel to the triangles and overlapping them. Repeat symmetrically.
4. Pull the inner flaps until they're vertical, and pinch the corners and new edges to sharpen them.
Step 2: Different Sized Boxes
Boxes can be made in any shape and size, to fit any need. For snacks, a large high walled box fits the bill, while for small components a post-it note can keep everything organized.
Step 3: Sticky Note Boxes
Sticky notes can make two cool different box crafts!
Folding a box with the sticky side down initially can create a sticky tray that'll keep small parts organized and attached to a surface (or your hand!)
Sticky notes can also be used to create gift boxes! Make the base of one box slightly smaller than the other, and slide them together with one box serving as a lid.
