To start, I applied my base coat and my base colour, I used Barry M Cyan Blue.
Then I applied 2 wide lines, one vertical, near one side of my nail, and one horizontal, across the tip of my nail, using Barry M Blueberry Ice Cream.
Next, with a nail art brush, I applied thinner lines, 2 vertical and 2 horizontal, using Nails Inc Hanover Street.
Then, using Collection 2000 Powder Blue, I applied another vertical line in between the two dark blue lines and another horizontal line at the tip of my nail.
Finally, using beautyuk No. 46 Blue, I did two more vertical lines and two more horizontal lines wherever I could find space, then applied my top coat.
You could try using a few different colours and see how that turns out!
Hope you enjoyed!
