When I was younger I would often doodle the same thing. I would draw a series of dots to comprised the outside of a circle, then I would connect those dots with lines, lots and lots of lines. Today's manicure is my interpretation of those doodles so many years ago. It kind of looks like tangled string to me a bit. :)
I used butter LONDON Billy No Mates as a base, with Essie Matte About You on top of it, then I used American Apparel Hassid and CND Anchor Blue to paint the line art.
