Ever find yourself wondering what to do with leftover used dryer sheets? Take a cue from the "frugal person's bible", The Complete Tightwad Gazette, and re-use/re-purpose them! Simply add a few drops of your favorite perfume, essential oil or even extract (such as vanilla) to the used dryer sheet. Or, you could really go DIY and cut up some of your husband's shirts he still has around from high school (I'm talking to you, Mr. S!) and apply the extract/oil/perfume. Just rub in the scent a little into the fabric/dryer sheet and voila!
