Wood is the hard by bark-covered tissue of trunks and roots from trees and bushes.

The composition and growth of wood are greatly divers, which result in a variety of characteristics of the different species: colour, drawing, radiance, scent, thread, volume weight, hardness and durability.

One of the main reasons why wood graining came into existence is because certain kinds of wood were hard or impossible to come by.
And an imitation of wood has the additional advantage that usual it’s cheaper than the original and a decoration is fully adaptable to the colours of the interior.
