I think these are cute so I'm going to share them with you.
the first thing I did was use Black by: Silk line and drew a half circle at the bottom of the nail, then I used a White to fill it in.
I picked Five O.P.I. colors, one for each nail so the green was "who the Shrek are you" the pink was "la paz-itively hot" the blue was "Orge-the-top blue" the orange was "in my back pocket" and the purple was "lucky lucky lavender. I added to eyes and voila! its that easy.
Hope you like it, let me know
