I am somewhat neatness-challenged so when I ran across this blog, 365daysofdecluttering, I welcomed the systematic process to decluttering my house.
ROUND 1: Weeks ago I wandered my house gathering "flea market-worthy" items. Rather than bothering with a garage sale or hauling to Goodwill, I posted a "Curb Alert" under the Free category on craigslist.com. You simply post a list of what you have and where to find it. As soon as the boxes are gone, delete your ad. It doesn't usually take more than 24 hours. (I don't live on a busy street so a "free to good home" sign might not guarantee my boxes would get picked up.)
ROUND 2: Today I tackled two small areas: the kitchen junk drawer and a shelf in my "studio" room that was full of good Curb Alert items. The only areas remaining are...every other horizontal surface in the place! Oh well, slow and steady wins the race!
