Keeping in theme with my pointy, pointy nails, I decided to try out an engraved pen nib.
Yeah I managed to do my thumb before I said, "Fuck it."
Don't get me wrong; the other nails are fine. They're just not engraved. And fancy pants. Yo.
I literally just painted my nails silver and then painted a black line on them. The engraved one had the addition of mixing the silver and the black to get a gunmetal-ish color, which I then used to draw a pattern.
I used a toothpick to draw. I don't recommend this.
