Wood carving is done on a variety of objects-ranging from furniture (tables, chairs, writing desks, dining tables etc.) to articles of personal use cigar boxes, jewelry boxes, photo frames and various other articles. Walnut is the most common wood used for carving. Kashmir is the only part of India where the walnut tree grows. Its color, grain and sheen are unique, and the carving and fret work that is done on this wood is of the finest quality. Walnut wood from the root is almost black, and the grain here is much more pronounced than the wood of the trunk, which is lighter in color. The branches have the lightest color, almost blonde, and have no noticeable grain. The intrinsic worth of the wood from each part of the tree differs--wood from the root being the most expensive. There are several varieties of carving-deep carving, usually with dragon or lotus flower motifs; shallow carving, done all over the flat surface; open or lattice work, usually depicting the Chinar motif; and semi-carving, which is a thin panel along the rim of a surface, with perhaps a center motif. The advantage of semi-carving is that it allows the grain of the wood to be displayed, together with the carver's skill. Wax polishing brings out the inherent sheen of walnut wood, and is by far the most popular finish. Since varnish obscures the grain of the wood and alters its hue, it is rarely used.
