Take your nail polishes. I've used.. Essence #70 'Nude it!' Essence #55 'Let's get lost' Two from a shop in my country called HEMA. And butterfly's #180 witch is an Hungarian shop.
Use your dotting tool for the first color blue.
Dot a dot :)
With the striped fade the dot out until this appears
Repeat the steps
There it is :) hope you liked :))
