My very first franken and it turned out great! I didn't think the polish that I used would work with the black but it did. I saw something like this on The PolishAholic, you can check out her post here.
I picked up a cheap bottle of Wet n Wild Wild Shine Black Cream, dumped about half out and used the pink holo polish I found here in Japan, then used thinning drops to smooth it out.
In the shade you can see it doesn't look like much.
Once it get in the sun it sparkles like mad. These pictures truly do not do this polish justice, it is ten times better than the pictures.
It shows more in this picture but it is a bit blurry and washed out.
I don't own the original My Private Jet and I can't bring myself to pay for it on Ebay and risk getting a fake so this will be my substitute for it. This isn't a linear holo but I still love it.
