Purple & Black Zig Zag

I came up with this purple and black mani as a combination of the zig zag from this mani and the half and half look from this one.  I started out by painting my whole nail lavender using Confetti Belle of the Ball, and then painted over half with Confetti Centerstage.  I added a layer of Seche Vite (because I wasn't patient enough for the polish to air dry), then added two triangles of tape and painted over everything with Sinful Colors Black on Black.  Then I removed the tape, and that's it!  This look took a little longer than I would've liked since it required three colors + top coat, but I like the way it turned out.
