This week the challenge was chevrons, now I have done these before back in the summer of 2012 here, and more recently in October last year here. So for these nails to be relevant to this challenge the polish used has to be over a year old.
I used OPI's Road House Blues which I got in October 2011.
Base Polish: OPI - Road House Blues
