Wall coverings and fabric offer yet another option to solid color in the treatment of decorative surfaces. A well chosen wall covering with complex coloration and texture can create a special atmosphere in a room, as well as add overall visual interest to a design plan when combined with opaque and decorative finishes. With very few rolls and relatively little expense, wall covering can provide the color palette for an entire decorating project. Where traffic and moisture are a problem, wall covering can also be more practical and maintenance free than a painted surface.
