Engineered Wood - Also called composite wood, includes a range of products made by binding
small pieces of wood together with a fixative to form composite materials.

Flitch - A log that has been cut, cataloged, and stored together, offering woodworkers the opportunity
to buy matching material from the same tree. Flitch sequences are utilized in veneer selection.

Grain - A term referring to the arrangement and direction of wood fibers. Among the many types of
grain there are fine, coarse, straight, curly, open, flat, vertical, and spiral.

Green - Lumber that has not been dried and therefor has a high moisture content.

of grain appearance and direction, a uniform finish, and economic flexibility.
