Thank you, to all who have commented! I do like the cabinet--mostly because it is slim enough to fit behind the door in the space I've allocated (in my mind, anyway) to the hanging organizer. Our home is so small that there truly is no square-footage on floor or wall to put boxes or cabinets.
Angie--I do not forget about the shoes--maybe because I have a relatively small collection? There are only 20 pair plus flip-flops, running shoes, and winter boots etc. Like everyone, I guess I do have favorites that I rely on more than others, but I look forward to dressing with some of the lesser-used pairs and have no problem sorting out the appropriate box. The boxes are labeled and I find that running my eyes over the whole collection is enough to remind me of my options.
Sal--I have two motivations to make a change: Firstly, the stacks of shoes are crowding the items that require full-length hanging space. I want to be able to see these items accommodated generously instead of crunching-up on top of the shoe boxes. I have added a couple pair more shoes this year, so that is a new issue. And, secondly, I'm getting a little tired of jiggling out the boxes from the middle or bottom of the stacks. Again, a new problem, I think, due to having increased the shoe collection.
delurked--I think I have a strong motivation to sort/group/categorize items and when I've done this--especially using attractive, matching, or intentional storage boxes--I feel tidy and put-together.
Sterling--we built a freestanding wall organizer using Elfa and it looks good and works really well.
