This is a part of the Llama Nails, Nerd Challenge. Second challenge is: Space.
One of the W7 polishes I recently bought was Space Debris. I wanted to do something special with this polish and grabbed my hex glitters for some added "debris".
First I started with two coats of Space Debris, and then I added some red and copper hex glitters on my nails and finished it with another coat of Space Debris.
I suppose this is what you call a: Glitter Sandwich (?)
