This one I just threw together at work, in lousy lighting, so it's no surprise it turned out a little meh. Thought I'd share anyway though.
I started with three coats of Covergirl Scalding Emerald (I'm obsessed with the glassfleck glosstini polishes! They're so shiny! Even though they run sheer I love 'em to pieces).
Then I did a brushstroke down the middle of each nail with Covergirl Violet Flicker. It didn't show up nearly as well as I'd hoped, so for a little more visual interest I added a french tip with Finger Paints Winter Chill.
