For the base, I used a baby blue polish by Julep and a baby blue glitter by Nails Inc. This Nails Inc one is from their special effect line and it has a cupcake with sprinkles on the packaging! How cute? I certainly agree that it does look like sprinkles on cute cupcakes.
I then took my dotting tool and painted on some polka dots in various sizes using a darker blue and silver polishes. I purposely overlapped some dots to make it more natural and effortless! The dots kind of look like they are dropping to the bottom at the nail tip right?
