Originally I was trying to do a marbling technique. After ruining my thumb nail trying to smudge the black lines with isopropyl alcohol, I decided that I liked the cracked design that I had going on. It reminded me of a broken porcelain doll. While the cracks are perhaps a little thick up close, they're quite visible from a distance, which I like. Another nice thing is that you don't need any special nail art tools. All you need is some nail polish and a Sharpie. These look great for every day wear, but could also be a nice addition to a Halloween broken doll costume.
Materials:
*Clear nail polish base and top coat
*White nail polish
*Black Sharpie
Directions:
*Paint nails with a clear base coat. Let dry.
*Paint nails with a coat of white nail polish. Let dry. Follow with an additional coat of white polish if needed.
*Once the white polish is sufficiently dry, use a Sharpie to draw cracks on your nails. Let sit for about half an hour or so.
*Carefully seal in the design with a clear top coat. I found that the Sharpie smudged pretty easily, although not really much worse than the nail art pen I had smudged when I applied the top coat. For a less smudgy alternative, you could use black acrylic paint and an ultra fine nail art brush to draw on the cracks. That's probably how I would have approached this if I had been shooting for this aesthetic from the get go.
