To do this mani, I started with two coats of China Glaze In The Lime Light (Neon).
Indoor - No Flash
Indoor - With Flash
I really like this color, it has a really nice subtle shimmer in it and it also doesn't dry as matte as most neons do. My camera wouldn't quite pick up the true color of this polish, it was somewhere between the two pictures above - not quite as bright as the flash, but brighter than the picture without the flash. Also, I apologize for my polish bottle... it's had a rough life!
To create the drips, I used Sally Hansen Black Out and used the polish brush to create the drips and dots. I just painted on a messy french tip and wiggled my brush as I dragged it down my nail in various lengths and then added one or two dots. It didn't take very long, and it was nice because you don't have to worry about keeping a steady hand because you want the lines to be a bit messy. I added a coat of Seche Vite top coat to seal in the design.
