Must...have...! How did she do that?? Konad?
I'm betting it was done with a few layers of gold polish and, after letting them dry completely, written on with a polish pen like this one followed by a top coat.
I did them by painting the words with acrylic paint onto a freezer bag, then adding top coat over it to make them into nail decals, then cut it to fit my nails. If you youtube 'make your own nail decals/stickers' you can find a handful of tutorials. :)
Thanks, Billy! They look incredible.
