Looking at this design I realize I probably could have done this as my Half Moon mani also, but I really like what I did for that design, so check back soon because I'm sure you will like that one too :)
The base color for this is China Glaze, White on White, which I do like, but I prefer Sinful Colors, Snow Me White. Overall it just applies more opaque. With the CG I have to apply 3 coats to get overall opaqueness, whereas with SC I only have to apply 2. The purple and green are both acrylic paints and the sparkle I added is China Glaze, I'm Not Lion.
So as I said before I absolutely love how this turned out! I am so happy with it! It's simple and elegant and super easy! This is a great design for any nail artist, beginner or more advanced :)
