How did u do it? ~~~~~~ I polished my nails with a very dark blue polish. Then I took a turquoise nail design polish (the one in the skinny bottle with the long skinny brush) and swiped from the outter edge of my nail towards the middle of my nail. I alternated- swipe from right side, then go up alittle and swipe from the left side to the middle- I did that all the way up my nail on each nail.
