"First apply a clear base color to your nails to prevent them from yellowing and make your nail color last longer. Paint the first line of color down the middle of the nail from the base of nail to the tip leaving a small space at the base. Then paint two strips on either side. Let dry before applying a second coat. Finish with a single layer of clear top coat to extend your manicure" Fiona Jolly, Maybelline New York's Celebrity Make-Up Artist.
