There has been a sale in the super market of Nordic Caps nailpolishes. Very cheap polish with good covering but a bit soft even after hardening. I found them in the local supermarket for only 1 € each. I bought the clear polish to make my own of old eyeshadows.
The grey polis is made of a grey very shimmering eyeshadow. I didn't use this much so this was a good way to get rid of it. The yellowish one is a golden powder to use were you need a golden highligt, so typicall the millenium. Also the semi transparent one in the middle is a highlight powder with white shimmering and blueish flakes in it. The beige polish is the matching loose eyshadow to the grey. I cant use eyshadows with this much shimmer. It makes me look older.
This is how the four ones looks on the nail. My long finger is painted with the beige one and my pointing finger is painted with the white shimmering. The coverage is not so good. You need 2 to 3 layers. The shimmering shades will be used for highlighting.
This is how the golden and the white shimmering polishes looks painted on top of black nailpolish.
You can also use glitter from the hobby stores if you would like to try to make your own polish.
