As you can imagine it was really easy to do, just OPI Lady in Black on the front of the nail and OPI Thrill of Brazil on the underside. Two coast were applied to each side to increase the depth of colour, and I found that the black on the front showed through on the underside, so a third coat may be require to deepen the red underneath but this depends on the quality of the polish that you choose to use.
Unfortunately I haven't been able to do it on my own nails as I'm a recovering biteaholic, but I'm getting there. I can't remember where I first saw this idea (probably on another blog) but I did a bit of research into getting the right red and I think that the result looks great. Let me know what you think!
