This design was really quick and easy to do, give it a try =]
1- Paint your nails black.
2- Cover them with a matte top coat and they should turn out like this:
(this top coat is my Oh So Nails from Next)
3- Now I was planning on using rhinestones, but I then realised that I have no idea where they are...so now, add your design using small silver spots and sprinkle glitter over them. (I used glitter from an old make up roller)
4- I had tried the design on every nail, but decided I preferred the bottom design, so kept it like that =)
