Here are the three colours I chose to use, all Barry M Jelly Polishes:
Here's how I got on:
I first painted my nails with the blue shade of polish,
Then using only the nail polish brush I painted a horizontal line across my nail and then filed in the space above the nail.
I tried to keep the placement of the horizontal line similar on all of the nails, I then got out my dotting tool and dotted around in a circle with the opposite colours and filled the middle with a slightly bigger white dot.
I think this design would have worked better if all my nail beds were the same size, as there would have been a better symmetry in the design. I think using a more contrasting colour for each half would have also created a more striking design.
Hopefully my next design will go a bit better.
