Envelope
Research project about eco-friendly packaging,  to reduce material consumption, inspired by origami philosophy.

------------------------------------------------------------------------------------------------------------------------------------

Concept
> Make two closed volumes with a "simple" square sheet paper, using minimum material.
> A secondary volume will fit into the primary one.
> Document all the steps to obtain these volumes (instructions).
> Protect those volumes with an original rigid box.

Constraints
> no glue
> no staple
> no cut

Only folding, time and ... patience :)
