Pine in general is a wonderful species to work with, it looks great, smells great and its hard to beat the charm that the natural warm colors that pine can bring to a room. What makes vertical grain pine special is the way it is cut into lumber or veneers. Lumber that is cut tangent to the annual rings with rings at angles 0 – 45 degrees with the wide surface produces plain-sawed lumber which is how most lumber is cut, lumber that is cut radially to the rings with rings at angles of 45 – 90 degrees to the wide surface or parallel to the rays produces vertical-grained lumber which has a very uniform pinstripe grain presenting a formal classy appearing door.
