If you have access to any old cotton muslin sheets, these make great re-usable window cleaning cloths. Just throw them in the wash after using them, and they'll be ready for the next time you need to clean your windows- free to use, and saving the expense of paper towels, too. Some people also used to use wadded up newspapers, but your hands will turn black from the ink if you try this.
A great idea to recycle newspaper: if you're used to peeling your veggies onto paper towels, instead keep a supply of half-sheet newspapers under the kitchen sink and use one of these when you're ready to peel. You're re-using the newspaper, and you're saving money on paper towels at the same time.
