328 Materials Wood Grain Grain We cannot gain a lot of straightgrain part from one tree. Places where branches once grew become gnarls, and the grains of such places wave. We place these wood characters efficiently on the surface of furniture so that they look attractive. Color Even though lumber boards are taken from the same wood, the color of the boards may vary for their places of the wood: outside or inside; upper or bottom. Aging changes Wood (especially solid wood) keeps on moving after processed into furniture. Table top boards of solid wood may warp or break. Even so, they can continue to be used by repair. Damages Solid wood furniture may be dented by impact or burned by heat. Even after such damages, it can continue to be used by repair: dents by steam heating; burnt places by whittling and painting. Random match Wood planks or veneer sheets are joined at random, of which expressive surface patterns require craftspeople for high skills and an eye for beauty. Book match Two pieces of wood planks or veneer sheets with similar surface patterns are arranged side by side to look like a book opened, which makes surface patterns look more dynamic by grains running symmetrically. Slip match The most simple but beautiful repeating surface pattern is produced by arranging in order wood planks or veneer sheets facing in the same direction. In most cases, straight grain planks or veneer sheets are preferred. Surrounding environmental effect Exposed to direct sunlight or hot air from heater, wood may suffer from color change or small splinters. Even so, it makes a comeback by repair.
