I wonder if O.P.I. or Katy Perry are closet crafters? Check out the latest KP nail polish collection, featuring Black Shatter. It works like Quick Crackle, the craft topcoat that causes paint to splinter and pull apart for an aged, peeling paint finish for wood surfaces. I am liking the look that Katy's nails are flaunting-- it almost has a animal print quality to it. Here's the drill: You apply one coat of Black Shatter over completely dry nail lacquer for a look that's totally Katy! Do you love it? Would you wear it? Can you use it over other paints to make stuff? Interesting possibilities!
