You know the type, you can hang them on the back of a door and there are several pouches for shoes, usually a dozen or more pouches. I use the clear vinyl ones, but you can also use the canvas ones and label the pouches with fabric paint.

I use one in the bathroom to hold hairbrushes, deodorants,extra shampoos, hair care products, etc., no more clutter on the bathroom counter or knocking things over on shelves.
I keep two in each of the kids rooms, one on the front of the closet door for small toys, and one on the back of the closet door for shoes,, gloves, scarves, hats,etc.
I cut one down to fit the back of my kitchen cabinet door and store packets of sauces annd seasonings.
Another great use is in the laundry room for odds and ends and those things we always find in pockets.
I also use one in the shed for small gardening tools, gloves, rags, etc.
Would love to hear more organizing ideas!
