Really wanted to get this challenge in before expiry. I have seen these images so many times on Pinterest and am so envious of the wonderful nails, nevermind the polish.
So, that said, I knew I had some graduated papers somewhere, this was the only one I could find, but hopefully you get the effect. And yes, my polished girl is making another appearance, as I always stamp a couple of images, in case of mistakes. Now I look at the photo, she doesn't pop quite as much as I thought she would. But her polish IS glittery.
