Thanks to one of my tweeps, I have been reminded of Nail Dust!
When I last used this it was relatively un-used, but now i have been reminded I am going to be using it a lot more!
You can buy some quite good polishes that give you glitter effect O.P.I i have found give the densest glitter look, but the idea of a glitter dust that is applied over a still-sticky coat of colour is a much better way to get a dense, texturized nail design.

Or for a DIY option, a base coat, slick of you rfave colour then dip your nail into a pot of glitter!
Remember to apply a couple of good, but thin layers of top coat over the top.
