PLASTIC WRAP MARBLE NAILS: Use glossy (Sally Hansen Hard as Nails works). Cut 10 pcs plastic wrap- it’s ok if it sticks together. Paint base color; dry completely. Put 2nd polish over 1 nail; quickly blot top of nail once/ twice with crumpled plastic wrap. When plastic wrap touches wet polish it pulls up some color, giving a marbled effect. If you pull up too much, add more polish & dab again. Then do next nail. Finish each nail w/1-2 more layers of clear top coat to smooth & shine.
