I would not normally call any time where I clean a "party" but the great people at Simplemom.net have a step by step two week spring cleaning regiment with day one starting today.
I just learned about this a few hours ago and jumped on the band wagon. If you're like me and need a little motivation and lots of direction when it comes to cleaning you might want to try it too.
Basically, Simplemom.net will post a new cleaning task (chore?) every day and a little motivation to go along with it. The idea is that by the end of the two weeks, with only a little work every day, your spring cleaning will be done.
