I agree with everything that's been said.
Maybe it would help to sit him down, duct tape him to a chair, and make him watch a few episodes of Clean Sweep, too.
Michellegiordano said the most important thing, I think - "You live there, too"
I am really into Neat, Room Service, & Mission Organization lately. And The Smart Woman Survival Guide. Its not really about decorating, but its still really good, its on the "W" network on mondays, and they play reruns most days too. Totally worth checking out!
Speaking of Organizing, I am still trying to do it, three years into my marriage, its not as easy as it looks on TV. I need a professional organizer and a whole bunch of money for all these storage solutions. I just finally got a filing cabinet last week, and what a life saver. The top drawer is a junk drawer, for junk we use alot and don't have a home for. The middle drawer actually locks and thats where I keep files, and the bottom drawer locks too and I keep bigger items like the spare keyboard and phone book (why do we keep a phone book anyways? - power outages - cause you can't look up phone numbers online then)
I have been wishing for a cubby shelf with baskets in every other shelf.
