A few years ago I went to a fascinating exhibition on plywood at the V&A museum (a design museum in London).

I didn't realise how versatile it is as a material. From chairs to boats to planes and construction - it's applications are wide-reaching.

This short video from the exhibition website explains how plywood is made:

"Plywood's unique combination of lightness, strength and flexibility has helped revolutionise design over the last 150 years, but its manufacturing process has changed little. Taking you on a journey from tree to board, watch our animation to discover how plywood is made."

And for anyone interested in the use of plywood by craft makers, designers, and architects, this excellent article from the same exhibition provides an introduction:

Exceprt from the above article:

"Plywood was particularly common as a building material in countries with an existing history of building with timber. It was deployed on a national scale in the USA in the 1930s and '40s."
