I painted my nails with two coats of Barry M Blueberry and topped with Seche Vite. I placed the studs into the top coat before it dried (so one nail at a time for busier patterns, especially if you're using a fast drying top coat!). You can also use nail glue if you'd like them to stay put for a while.
You can find these studs (available in a large range of neon shades) here. They are really versatile and can be used to create all sorts of effects and shapes. If you use the code UKX31, you'll get 10% off of your order too! :)
