I'm a few hours late on this one. I was getting ready to publish a Halloween post when I remembered Monday was a challenge day, and ghosts, at that, which I was stumped on. When I made the realization, we were on our way to see Adam Ant, so I had no time to do challenge nails.
I decided to do craft store micro bead ghosties! I have three coats of the purple glow-in-the-dark pumpkin polish with China Glaze White On White making the ghost shapes, then silver micro beads on top of that. I used black/greenish glitter circles for the eyes.
