To make this design on your nails, use a nail art sponge to create texture. You may use a white or pale pink polish as the base coat and then apply a textured marble design using a nail art sponge. Begin by applying the polish to your fingernails and letting it dry. If you are using the white polish, seal it with a topcoat so that it stands out even more. When creating the marble design with the nail art sponge, use any design you like. Nail artist Chaya Shurkin suggests trying out the classic diagonal pattern.
