Concrete Canvas

This is the material I originally attempted to work with for this class. It is a concrete-impregnated layered fabric with a waterproof backing that is flexible and bendable but fully hardens 2 hours after becoming wet.

Here's the site: www.concretecanvas.co.uk

And here are some design-oriented uses of the material: http://www.concretecanvas.co.uk/Docs/CC_Design_Brochure.pdf

Unfortunately, the manufacturer is based out of the UK and has limited inventory at the time, and a 1 sqft sample will set you back $10 plus shipping.
