COMMENTS: When I first got my dotting tool, I searched google images for inspiration and came upon this site: http://www.patternsshop.com. This particular mani is inspired by this image, which they actually have in three different color ways. I'm including a screen shot of the image below as well for those who don't want to click the link..

My inspiration - yah, I basically copied the pattern!
Used Nyx Girls - Perfect Gray and FingerPaints - Paper Mache for the dots:
