Today in the R31DC is half moons. I've done a tutorial on tradition half moons here. And here is another version:
I started with two coats of Orly Rage, a beautiful, light copper shimmer. Once that had dried completely, I cut out triangles out of scotch tape:
Then using the gorgeous, shimmery Zoya Jem, I painted one kind of thick coat. Paint your nails one at a time and remove the tape before going on to the next nail. Then just finish with your favorite top coat.
