Once the girlfriend (maybe ex-gf?) of my cousin made my nails like this.
I think this nailart technique is pretty cool, so I wanna share it with you guys.
~Let's begin ^^~
|Begin with clean nails and apply the base coat. (optional)|
|You have to cut your sponge in a size that fits good on your nails.|
|Apply the two colors (or more) on the sponge.|
|Dab it on your nails. Don't worry to be messy :D|
|Wait until it's semi-dry and apply a glitter nailpolish (use one which has bigger flakes) [!]|
|Clean up the edges and ....|
There is also another way to achieve a nice gradation which I will post.... someday :D
