I've been looking at Noah Scalin's 365 skull project a lot lately. So I painted skull nails! I used L.A colors art deco purple and white for the skulls and I did the background in a steely black. If you wanted to do these you should probablly do like a circle and then a rectangle overlapping the circle instead of just doing the whole thing like I did. It would be easier to keep them the same size if you did it that way I think.
