All you need is an old makeup brush. Clear polish and some glitter.
Simply paint a base cote on your nails then dab the brush in the glitter and dab on wet clear polish.
Might require a couple of coats. But it's super effective and lasts too.
Finish off with 2 clear coats of polish to seal the glitter and voila. At home disco nails
I brought the glitter for another project. But it worked perfectly and was from eBay for £1.99 delivered for that massive bag !
Well worth it and now I have pretty toes.
