Anyway, onto the nails.....
For letter K I used Spoiled Kickin' the Habit, a neon fuschia. I was not a big fan of this at all. The brush absolutely sucked. It was more of just a big bushy thing rather than a brush. Also, depending on which way you turned the bottle it was a different color. And the color in the bottle was different than the color on the nail. I shook it up so much and I still felt like the pigment wouldn't mix up or something. Ugh.
