I started with a white base (Snow).
Then I used a striper brush and 3 colors (Blue no blues, 268, 311) to make random stripes on the nails (starting from the left side and right side of the nail).
I then took a detail brush and Snow to make the letters and flower, butterfly designs.
I found the white didn't stand out enough and decided to inline it with Deep Violet using the same detail brush.
Seche Vite and done :D
