Here is my most recent effort to do space nails that look like these. This time, I kept it simple and used only two colors: Orly Star of Bombay (a navy blue cream) for the background, and for the stars and space dust, I used Wet n' Wild French Creme. Techniques were sponging using a makeup sponge, and dotting using toothpicks and dotting tools. I made the dots as small and irregularly placed as possible. I think this is a pretty respectable result, but I'm not quite satisfied yet, so I will probably do at least one more space nails post!
