The wainscoting and picture frame collage extends up the stairs and down the hallway. I spent a few weeks creating the wainscoting. It’s MDF that I routed with a “Roman Ogee” bit. Then I spent another week priming, sanding and painting it. It took a few days painting and hanging all the picture frames. Not too bad in terms of time/work for the impact it created. I love having it extend all the way down both the upstairs and downstairs hallways. It adds texture and the white and bright paint make the hallway not seem super narrow.
