I really dislike those long pins, but this is such a great idea, I'm pinning it anyway. Easy Cardboard Box Organizer. Shown here, it's holding shoes, but you could store anything: magazines, files, craft supplies, etc. I would also cover or paint it rather than leave the plain cardboard.
Upcycled Kleenex Box - cute idea, this would be great to put in areas where you keep little things lying around like your keys by the door or the mail. Also would be super cute in my craft room to store pens, scissors, etc. i'm not sure I could do the liner though. I need to learn how to sew!
