Unsuspecting black nails, right?  Not so.  A couple weeks ago I saw THIS link on facebook and just had to try it.  I know I will never own a pair of these heels, so I'm living vicariously through my nail art.  It was actually a lot cleaner than I imagined it would be.  I thought my whole finger tip would be covered in red polish and there would be tons of clean up.
I made sure to slather the under belly of my nail with a base coat in the hopes that clean up would be a bit easier.

I love the peek of color underneath.  I don't think it's real practical for every day wear, but fun none the less.

Here's a look at what it looked like right after I finished my clean up (plus base coat).  I took a cotton swab and my clean up brush to it then scrubbed a bit with a nail brush and soap and water.  It was no more labor intensive than a stubborn glitter.  This could definitely be fun in a whole combination of colors.
