Like Pam, I've been doing this for so long, I don't really think about it anymore. However, in addition to the plastic boxes (I actually don't use too many of those), the white vinyl-covered wire shelves are quite useful in utilizing the many too-tall cabinets in these things ... and you can stack the plastic boxes on them too!
Storage organization is one of the many things I'm rather anal about and I like to have things as close to where I'll be using them as possible. And, it drives me insane when I can't find something ... these things are too bloody small to lose things in!
Even though Steve complains about all the pillows we have on our bed, they are quite handy on travel days for keeping things from moving around.
I love the challenge of finding room for our stuff ... I would love to go to your place and help you!
