I had cut down one of my old nail art brushes to see if it would help me achieve a thinner line. This was just a quick design I came up with in order to test it out.
Firstly I painted all of my nails with 2 coats of my base colour. I went for a purple shade.
Then using a silver colour and a thin nail art brush, I added some curved lines to each nail.
Then I repeated this, but with a multicoloured glitter nail paint. I added the lines in between the silver lines.
I then finished everything off with a top coat.
