To get your nails nail-polish-ready, click here for some tips! Now, all you gotta do is start off with a base coat, then paint your nails one or two coats of the light polish choice. (I also did an accent nail with reverse colours.) Let that dry before creating your dots with your dark polish. I used a dotting tool, but if you don't have one of these, simply bend open a bobby pin and use the plastic coated tip. Wait a solid hour before applying a top coat in order to avoid smudging the dots, and there you go! A neat variation idea would be to use little rhinestones instead of polish dots.
Let me know if you give this idea a try!
