Get a long-handled duster (or a regular duster and a chair!), and dust all of the A/C vents in the house. It might help to turn off the A/C first! If you add this quickie to your Monthly Cleaning Schedule, it will help with allergies, and dust floaties when the air is on.
I sat down last night with my pretty, purple blogging notebook and a matching purple pencil and went to work listing all of the Little Things I could think of. I made a pretty healthy list of about 50 things. I also stopped at the Library for some books on Weekend Organizing and Quick & Easy House Cleaning to help me with some more ideas. The research part is fun for me, even though I should probably be studying, or working on Crochet Booties.
