I saw someone else do this on the internet, so I can't take credit. But, I HAD to try it out :). List of polish: OPI for Sephora (pink)- What Aura Gonna Wear?, OPI (orange)- Pumped Up Pumpkin, OPI for Sephora (yellow)-Yellow My Name Is Betsey, OPI for Sephora (blue)- Too Too Turq, OPI for Sephora (purple)- Eve-y on the Eyes. After I sponge Ombre-d it (if you will), a coat of Seche Vite to smooth the surface. Then the water marble of simply OPI Black Onyx and OPI Bubble Bath (sheer beige...helped mask the edges of where the colors ran together) Then finished with another coat of Seche Vite. I really LOVE how they turned out. Hope you all do too :)
