I cannot rave enough about the Sinful Colors nail polish line! This stuff is fabulous, and very inexpensive (only $2 a bottle at Target)!
Here is my most recent change. I put down a black base coat, and then topped it off with a couple of coats of "Nail Junkie" from the Sinful Colors line. Here is a pic of the polish bottle. So sparkly! How can you resist?!
While the polish is still tacky, I put on my top coat. Then immediately, add your jewels. I chose to alternate between small and large, and light blue and dark teal. Here is the finished results!
I wore these nails with a black and white outfit accented by teal tights. (see my birthday outfit here)
