I really love how these turned out, the pink and yellow gave it an 'inside the nebula' kind of feel. I used a bunch of different polishes:
First I did one coat of Gap Peacock Blue as a base, then sponged on Spoiled by WnW Are Mermaids Real?, Revlon Royal, Color Club Port-Folio, Color Club Model Behavior, Wet n Wild Tropicalia and Spoiled by WnW Designated Driver. Then I did spots of white using Milani White Canvas Nail Art polish and topped it off with a coat of China Glaze Fairy Dust for some sparkle.
I used a crystal my mother sent me as a prop, I think it complements the mani perfectly!
