Watercolor is one of the most demanding forms of conservation and restoration. In almost all watercolors the white of the picture comes from the background since watercolor has no "white" for the artist to utilize. For this reason, the ability of the restorer to deal with significant problems in the white area of the watercolor is critical. And as well, the restorer is dealing with a medium that is extremely delicate; there is little room for error in Watercolor. Restoration By Heart has performed restoration on many watercolors by major artists.
