Appropriate Methods of Surface Enrichment for Wood There are three distinct means of ornamenting wood: (1) inlaying, depending for interest upon the difference in value and hue of the different inlaying woods used; (2) carved enrichment, depending upon line and mass for its beauty and made visible by contrasts of light and shade; (3) painting or staining of the surface with the interest dependent upon the colors or stains and their relation to each other and to the hue of the wood.
