I am wanting to do a small accent wall with tongue and groove 4 or 6 inch wide vertical boards but cannot locate any kind of wood like that. Long ago it was popular in knotty pine and I have seen it in offices in which walnut and other woods were used. I assume that it was not purchased as raw lumber and surfaced and routed or run through a shaper by the finish carpenters. The BORG stores don't carry anything close to that. Any suggestions as to sources of tongue and groove wallboard??
