Our little hallway between the kitchen and dining room which now sports the fun wall gallery, also had the feeling of being a hall of doors. It was only two doors but with the mirror, it seemed like 4. Not sure we can ever totally avoid that feeling but I was getting really tired of having people accidentally open the coat closet which is usually stuffed to the gills and hard to close (it's on my to do list!).
Here's the new house of doors but with a label to direct people to where they are supposed to go. I wish I had a little sign that says "private" on the other door. Just kidding. Kind of.
