I was experimenting with sponging on black and this one made me think of a night sky or a galaxy.
This is four polishes layered over one another. First one is a coat of China Glaze Liquid Leather. I used a makeup sponge to add China Glaze Splish Splash. The second and third polishes, both holographic glitters, are Orly Crazy Diamond and China Glaze Fairy dust. Fairy dust is my favorite micro holo but sadly it has been discontinued. I still find it from time to time on amazon :) Crazy Diamond is also a favorite but the glitter is a little larger than the tiny little shimmers in Fairy Dust.
