Multiple stripes of different colors of crackle polish with the top layer being a full coat of black crackle. The same effect could be achieved by using regular polishes to do stripes on the nail then topping off with the black crackle.
hHolidays are always a great excuse to get creative. here is a of july inspired manicure. use stick-on nail polishes in blue and white nautical stripes. then add one simple solid red nail to each hand or tiny little hearts!
