I thought of this design after looking at the illustrations by Brett Helquist in A Series of Unfortunate Events by Lemony Snicket. Specifically, The Ersatz Elevator. The crosshatch shading on, well, everything inspired this design.
First, apply your base coat. Then, use a striper (preferably white) and make two lines crossing each other at a 90 degree angle. This step is optional, as the white lines will only be guidelines.
Fill in each of the four quadrants with four colors. I opted for a slight pastel theme, using two coats for each color.
Next, using a white striper, create three diagonal lines on one corner of my your nail, and then three more lines on the opposite side.
Then, make three horizontal lines in between the diagonal lines, and repeat: diagonal, diagonal, horizontal until you reach the base of your nail. Finally, clean up, add a top coat and finish!
The colors I used from left to right are: Wet n Wild On a Trip, Sally Hansen Xtreme Wear Mellow Yellow, Kiss Nail Art Paint white striper, NYC In a Minute High Line Green, and Wet n Wild I Need a Refresh-Mint. My base coat is Zoya Anchor, and My top coat is Sally Hansen Ultimate Shield base coat and topcoat.
