If you're going to leave a deliberate scent article, don't use something that was in the laundry hamper mixed with other people's clothes. And if possible, use something that isn't loaded with perfumes from the detergent and softener. Just take a clean cotton handkerchief and tuck it inside your waistband, next to your skin for half an hour or so, the drop it in a ziplock bag. Leave it on the seat of your car, labeled 'Joe Smith, scent article'.
