To control the grain of boards, saw mills pay special attention to the direction in which a log is cut. The most common method for cutting is the quarter sawing, which will cut a log into even boards that form parallel plains. The lines of the grain will appear to run consistently along the length of the board. Flat sawing is the other most popular method for cutting logs into usable shapes of lumber, but the grain patterns it produces are considered unappealing. Therefore, flat sawed lumber is used for internal construction. Finishing wood and veneers are often created using sawing methods like rift or radial because these allow for greater control over the grain direction, which increases the beauty of the finished wood project.
