First, I started with painted the entire nail a light pink color, but because I wanted a deeper pink color(Lilac Silk) on the nail, I did 2 decently thick coats. After the pink dried a little, I painted the tip in a french manicure style with Black polish(CoverGirl Midnight Magic). I did the black in 2 coats too to also get a deep, rich color. After the tip was dry, I used the black polish and a precision fine tipped brush to draw lines diagonally from the black tip to the nail top, as seen in the pictures.
After the first set of lines dried for a minute or two, I drew on the second set of lines, going diagonally from the opposite direction the first set of lines went, as shown in the picture above.
