I’ve done a couple of variations of glitter gradients on my nails before (using a sponge and shellac { here }, and using layering { here }), but I think this most recent way is the easiest yet (using shellac polish).
I started with a nice neutral base colour.
For the gradient, I used gold glitter shellac polish, a small amount of rubbing alcohol, and an artist brush.
I first added the gold polish to the base of my nails with the small brush. Then I dipped the brush in the alcohol and pulled the polish forward, creating the gradient effect.
Happing polishing!
