Continuing your hijack...
I never do garage sales anymore. I am now a Craigslistian. You have a digital camera, right? What I do when I clean is carry a paper bag or laundry basket from room to room with me, and drop whatever I can live without into the basket. Then I take a picture of my stuff to get rid of, post an ad on
http://www.craigslist.org (there is a site for Milwaukee, if you live near it, and I think Madison), then store my "Craigslist" stuff in a spare bedroom until it sells. Whatever doesn't sell by the time I get sick of looking at it in the room goes to Goodwill a few times per year.
Another great organization for clothes is Dress for Success, which helps low income women obtain professional clothes.
