I started with applying a black base on the accent nail (China Glaze Liquid Leather).
Then I applied a large blob of UV topcoat on my tip and used a striper brush to drag the topcoat up to 2/3 of the nail (simular to the needle dragging method).
Of course trying to make some flames like movements.
The base being still wet.
Then I applied another blob of black polish on the tip and did the same thing.
Only the black I dragged less up to the nail to 1/3.
Now, this nail art looked nothing spectacular in real life but next to the UV bulb...
