Wood Patterns are a type of decorative art that involves the use of wood to create intricate designs. The patterns are usually created by cutting, carving, and burning the wood in order to create a unique design. The most common type of wood used for these patterns is hardwood, such as oak, walnut, and mahogany. The term 'grains' refers to the direction of the wood fibers, which can be used to create different patterns. Grains can be used to create a variety of textures and patterns, from smooth and uniform to rough and irregular.
