We are building a cabin and are planning to install knotty pine on the ceiling. We would also like to use it on the gable ends of our cabin. One end is a loft area with a bed room,with foot walls. Over the kitchen and living area is open to the ceiling. We are not sure where to start if we would like to install the knotty pine diagonally on the end wall. If you could help us out, that would be great.
