My cube is next to the window, so there is a cube wall that runs parallel to the window. I found plastic clips with stickpins that stick into the cube wall fabric. Each morning I hang my wet towel on these plastic clips on the cube wall, but since it is only six inches from an exterior window, nobody notices the towel hanging back in there. I take a dry towel out, and hang a wet towel. So the dry towel comes home with me each night.

For my clothes, I am fortunate that we have a shower and locker room, and there is a three foot long clothing bar. But I have to bring my own hangers, as the cleaning crew disposes of any empty hangers left on the clothing bar overnight. I left a sign on the wall to please leave just two empty hangers for the biker's use. But next thing I knew hangers started to accumulate, and then obtuse users started hanging wet nasty gym clothes and leaving them hung there for days, even though the official rules posted on the wall states the locker room is for DAY USE ONLY and no articles are to be left overnight (including empty hangers, I guess). My simple request quickly became fodder for the ignorant and inconsiderate. I gave up that battle and now I have small plastic hangers packed in my panniers which I must transport to and from home every day.

The moral of this story (and some of the other responders) is, there are little hidy-holes around your office you may not have noticed before. Just keep looking around and you will discover them. Look for places where your stuff won't be noticed so it won't get thrown away, but has access to enough air to dry and not smell too bad. Utility closets, machine rooms, spaces between cube walls, etc. Just seek and ye shall find.
