A heptagon or septagon is a 7-sided polygon and this box contains 7 sides. The design is again, by Tomoko Fuse, from her book ‘Joyful Origami Boxes‘.

The folding is somewhat similar to the hexagon box I had folded earlier. The main difference is in the way the angle is decided for a heptagon.

Since the box has an odd number of modules, I think it looks better if made from a single solid colour or from a single patterned paper. Using alternate colours means there were will be 2 modules in the same colour which stands out like a sore thumb!
