I just love it when I can hang something without making a hole in the wall! With 3M's line of Command products, you can do just that. In addition to the various hooks they produce, they have shower caddies that attach and STAY attached to a wall that gets wet. They even make a spice rack that does not require nails or a drill to hang it!
If you think out of the box, you can use some of these items in other areas of your house for storage/organization (i.e. craft room, home office, etc.).
