Well, was practicing on fake nails today and decided to do patterns of mermaid/ fish scales and I went for a lighter tone palette such as mint green, light yellow and white. From the first picture below, I have painted one layer of white and let it dry before using acrylic black paint to outline the scales pattern. After which, I applied on the green and yellow nail polish colour.
As the color was still quite light, I applied a 2nd layer of colour and waited for it dry. Meanwhile, if you noticed a bit of 'bumps' for the colour applied and the surface appears alittle rough. Don't be afraid, you always have topcoat to smoothen it out. While drying, I used a silver glittery nail polish pen to go over the lines drawn.
So, after the lines drawn, wait for around 5minutes before applying the topcoat to prevent the colours from spilling over - waiting for 5minutes ensures that the colours are slightly dry. Then apply topcoat to smooth out the 'bumps'. For topcoat, I use Seche Vite dry fast top coat.
Ta-dah! Smoother-looking nails. But I'm not done yet, it's only halfway through. Will post up the pictures after I'm done! :)
