Corian is an amazing material for house signs and it can be cut into most shapes.. It looks and feels like stone but has none of the imperfections you find in natural stone. The lettering can be smaller, images with finer detail can be used and it is less likely to crack or chip. It is available in a range of colours and two thicknesses. For more impact it can be placed on a backing board or put into an oak frame. http://www.sign-maker.net/engraved/engraved-signs-corean.htm
