I used what I call my Polish20 Whiskering Method™ which is fool proof and guaranteed to produce nice results. Are you creatively challenged? Lack of a steady hand? Use complimenting colors and stroke the brush quickly across the nail. Don't worry about being neat. Top coat with a clear or glittery polish and done.
I used Miss Bossy Pants (fuchsia), Slushied (blue) from the Sephora Glee collection and Paper Maiche by Finger Paints.
