These are some butterfly nails I did a while ago. Instead of the usual monarch colors, I used a more blue/purple gradient underneath the black outlines. Using Sally Hansen Lacey Lilac and Wet n Wild Putting on Airs, I created a gradient, added a topcoat, then used black and white acrylic paint to create the wings.
I’ve seen countless nails using this design, so I’m not sure where it originated, but credit to whoever did – It’s a really cute design!
