You found a $20 bill -- now what?
Best buy for $20? Clean windows, says Christopher Lowell, designer, author of "Christopher Lowell's Seven Layers of Organization" and host of the weekly Web series "Ask Christopher."
His pick for the job is a garden hose attachment that holds window cleaner and turns your hose into a window-washing machine. It's a great move, especially for summer, he says. "You don't realize what an emotional uplift it is when you walk into your house and see all your windows clean."
