This document provides instructions for folding a simple box from a sheet of paper. The sheet should be 10cm x 14cm to produce a box with a 3cm x 3cm base and height of 4cm. The instructions include 8 steps to first make valley and mountain creases at 45 degree angles, then lift the corners and fold the triangular flaps inside to form the box shape. When complete, the box can be flattened slightly to avoid tearing.

2. Mountain crease (try not
to crease center square).
3. Mountain crease at 45
degrees (flaps do NOT
meet at center line).
1. White side up. Valley
crease at 45 degrees.
4. Creasing finished.
Lift four corners, using
creases from steps 1 & 2.
5. In progress.
6. 3-D box-shape.
All triangular flaps inside.
8. Side view. Valley down on
creases from step 3. You may
need to flatten the box slightly
to avoid tearing.
9. Done.
7. Top-view. Push small
triangular flaps against wall,
then large flaps. Tips of large
flaps need to be folded a bit.
