I decided to play around with the two Katy Perry glitters, Teenage Dream (pink) and Last Friday Night (blue). Using some knowledge I picked up in... let's say preschool, I decided to see what kind of purple I'd get if I layered the two. Here's the result:
Pink Purple Blue
The first has only one layer of blue, the second has two. One layer of everything else with OPI's Alpine Show underneath.
It's fun plain and simple. It reminds me of cotton candy (if cotton candy were super glittery). Took about ten minutes to do, too, so that's a bonus.
