The prompt for day 30 is inspired by a tutorial. There are so many amazing tutorials out there from so many talented nail artists; it took me a while to choose one. I narrowed it down by choosing an artist first. That helped.
I chose a tutorial posted by Sveta Sanders on YouTube. The nail polishes I used are Julep Rose, Zoya Tanzy, and Anise Cosmic Kiss. My design didn't turn out quite as marbled as her's did. I should have chosen more contrasting colors. I still like it, though.
