Step 1. Paint your nail with a base colour. I used the new Bourjois 10 Days No Chips Colour in No14.
Step 2. Dab random blobs of your second colour over the nail - two or three on each nail works well. I used Rimmel Lycra Pro Nail Polish in Aqua Cool.
Step 3. Finally, using a nail art pen in black, colour around the blobs and create other random 'U' shapes across the nail.
Step 4. Finish with a high shine topcoat.
