> Gluing multiple panels together so that the corrugation alternates by 90 degrees every other panel makes them more sturdy, with wheat paste (1:5 mixture of flour and water) recommended as adhesive.
> Other tricks are folding over edges help to protect against damage, and integrating wood supports. Normal woodworking tools like saws can cut these glued-together panels. Adding the wheat paste to external surfaces can also protect against damage. By applying papier-mâché skills, a custom outside layer can be made that can be sanded and painted for making furniture, etc.

InventWood has a "superwood" densified wood product that's 10X the strength of steel.
HempWood is a compressed tensile fiber product that's 20% stronger than Oak dimensional lumber of the same dimensions.
