We are short on closets in this old house, and we have no real basement or garage. Technically, we actually have both, but the basement is just a dirt hole and it freaks me out (plus feral cats live down there in the winter . . . don't ask), and the garage is out across the backyard and not very secure. So, we are limited to pretty much just keeping our stuff in our two floors of the house.
I despise clutter, and feel that I'm constantly battling it. Anytime I can find a way to get some things up off the floor or another surface, it feels like a triumph! I got this idea from my sister, who did it in her old guest bathroom with extra toiletries.
I took an over-the-door shoe organizer and filled it with baby supplies: lotions, washes, medicines, thermometer, brush, comb, diapers, etc. Works like a charm for diaper changes without the extra space taken being taken up by a changing table!
