My air freshener sales more than doubled last year. I use the air freshener blanks. I'm still not getting rich from sales of them alone, but I am finding that more and more people are enjoying picking their favorite scents to fragrance not only their cars, but their bathrooms and closets. I have customers who hang them from towel bars, from hooks in their closets above their clothes, on their rear-view mirrors, car door handles, air vent knobs, etc. I had a customer order 20 of them for Christmas to hang (unwrapped) on the outside of Christmas gifts, as a little extra something for the gift recipient. I love making them and my customers really like using them, too!
