Stair Skirt Board Length
We are working on a remodel/addition. The stairs have been built and drywall is in. We built the stairs with a 2x4 on the side of the stringers to offset the stringers from the wall. This allowed the drywallers to drop the drywall right along the stairs and also allows for me to drop the skirt board right alongside the drywall without needing to scribe around treads.
My issue/question is in regards to what type of board to actually use for the skirt. I have a scrap of 1x12 and that looks like it would be a good size board but the longest piece of 1x12 readily available is 12'. I will need closer to 14' to span from top to bottom. What is my best option? Edge joining two shorter boards? Finding a 14' board somewhere? I'm just not sure how it would look to join together two boards. I figure I could either do a 45* bevel on each and join them or use pocket screws, but just not sure which would be best or what is normally done in this situation.
