Next time someone wants to give you their unwanted business card, don’t decline or toss it! Keep a collection of business cards in your vanity for mascara application. Since mascara should be applied last as a finishing touch, it often can create a smudgy mess. Avoid this by placing a business card right up against your lash line. Apply mascara as usual, only the excess makeup will smudge onto the card instead of your perfectly shadowed eyelids!
