Robin Moses inspired game of Tic Tac Toe

I have wanted to do chalkboard nails for a while and finally got my chance today.  I began with a black polish (instead of using green) from Love My Nails Black Rage 588 (and the bottle resembles my finished product which made me smile).  Then I used white acrylic paint and really tried to make thin, thin lines but they are very difficult to do with my current brush.  So I just ended up doing only the hearts and no x's to win each game.  Love always wins right?  Afterwards I used my matte top coat to give it the blackboard look (it removes the shine from the polish; just don't top coat afterwards or it will bring back the shine).
