A reader asked me about wall mounted laundry hampers, and I have to admit I had never heard of them. I did a bit of research, but all I could find was a sort of laundry bag that can stick to the wall with a suction cup. It is in the same style as hanging laundry hampers, designed to hang in a closet.
