I saw this design on Instagram and thought I wanted to try it out. I had no idea how it was done, so it took me three times to get it right. Basically, I just globbed on the light grey, blue and purple and swirled it around a bit with a brush. I cured it when I was happy with it, and then went back with some diluted light grey to soften up the look a bit, and cured that. Then I went with some gold leaf and made it look a bit like veins, and voila. Done (after putting a top coat)! I LOVE THESE NAILS.
