To do these nails I used striping tape because then it was easier to make the checkered diamond pattern with the red and blue, and it also allowed for the pearly white to show through when I took off the tape. I purchased the striping tape from Amazon. If you search "nail art striping tape" you should find plenty of options to choose from.
The pearly white is Sinful Colors Tokyo Pearl. The red is Sinful Colors Ruby Ruby, and the blue is Sinful Colors Midnight Blue. For the details inside of the diamonds I use acrylic paint because it was easier to work with paint since the area that I was trying to put the design in was so small.
