For this look I used the Painted Polish Drunk Striper over the top of Bliss Polish Catch me I'm Fallin'. I started off by drawing the outlines of the large triangles first. I retouched a few lines that were out of bounds and then added the second outline. Once I was happy with the placement I filled in the larger triangles. I found that the striper is fairly easy to use as long as you don't rush it.
