For the last five years, there has been a shoe organizer hanging on the back door. I think the people that lived here before us used it to keep their shoes when they came in from the garage. We used it to store a few items, but it wasn't really used efficiently. I would love to buy a railing and do this in a few places for my sewing equipment. I might down the road. I really like how easy it is to install and how little space it takes up.
I am sure that over time, I will be so thankful I spent the money and have this organizer... especially since it is easy to move if I decide I don't like it where it is at. It would be great in a closet too.
