I've been seeing Keys decorated with nail polish online as a DIY project. I was going to try that today, but as I was doing my nails and taking a break from reading The Hunger Games, I thought--Hey! I could use these Sally Hansen Salon Effects strips that I'm putting on my nails instead! So I did.
Basically when I use salon effects strips I only use one part of the package, leaving the other one for an additional use. I cut the strips in half and there's enough for all 10 fingernails. But there's always an extra strip. I used that strip for the key, then covered it in clear polish. Covered the top with a bit of black. Taa-da! A snazzy, lacey key.
