Made with the Max Factor polishes from the swatches I posted earlier. All you need are three polishes and some different sized dotting tools, and a brush (or anything) and remover to clean up around the cuticles.
I just polished the nails and then added the dots. On the thumb, the blue dots are larger than the red ones, on the other ones the dots go from large to small from the upper left to the lower right.
And then I decided I found it not interesting enough, and added some dots in gold, with Essence’s Go Bold.
