I got this idea from the boards last year, tried it and LOVED it! We bought an inexpensive vinyl shoe organizer that you can hang on the back of the bathroom door. When we unpacked we organized all of our toiletries in the shoe pockets. Because it is clear vinyl, everything is easy to see, and you don't have to worry about putting wet things inside. Also, no need to worry about things falling over, and it keeps the clutter in the tub and on the vanity down.
Just thought I'd share!
