This is a good way of using all your old nail polishes!!!
First start by painting your nails different shades of really dark colours.
Choose a mixture of bright colors you have that need using up.
You will need a white!
Now simply take a drop of nail polish and a tiny makeup sponge...
Dab the color onto the sponge....
Create Nebula shapes using one focal point of the nail as the main part and fade out, this is ridiculously easy using the small makeup sponge.
Add yellow or orange to the focal point to make it stand out!
Use other bright colors to make the center pop out.
You can go over the edges with black if your Nebulas need some definition...
By this point you will have used about 2 minutes of your time.
Add a couple of white dots ( stars) and a layer of glitter for some extra stars!!
Job done, i personally love this :) eeeeeee
peace and love
