Let me apologize right off the bat for the less than stellar pictures. There is no natural light in this hallway at all.
The contractor had taken it down to install the tile and when they came to put it back up I told them not to bother, I had a better idea. I had an old twin duvet cover. It was the perfect length (with a little pooling, which I love.) I just stapled it right to the molding, again, using inverted pleats because i *heart* them.
To finish it off I made a "fresh linens" sign and nailed it right over the top of the pleats, again, straight to the molding.
fell through it while prepping the attic for insulation and get the trim back up, but for now, the the fresh curtain and the fresh sign lighten the space and function better than a door blocking another door.
