So was the galaxy named after the candy bar or was the candy bar named after the galaxy?
Anyway, this manicure took approximately a million years, but I love it!
I used this wonderful tutorial by Through the Wormhole and started with a Fresh Paints dark purple named Witchcraft with my favorite sheer CG's Jetstream over it. Then I sponged just about every color imaginable over it and added white, toothpick stars. A lot of people who do galaxy nails make a lot of nebula areas, I tried to keep mine slightly closer to the night sky.
