Just something I came up with a a few weeks ago that I wanted to share. I used My Vampire is Buff (OPI), Eurso Euro (OPI), Jade is the New Black (OPI) and Mint Candy Apple (Essie) to create this looking. Believe it not, you can actually do this with just a toothpick. The trick is not to be a perfectionist and let the polish do its thing.
Hope you like it!
