Today was a new one to me! I had to google it lol!
I think I have used Zoya Blu every day so far lol!
Blu is the base and Barielle Surf's Up is the dark blue. This is a nerve-racking mani to do. One hiccup and it's ruined lol! I like it thought, it's fun and different.
Be sure to check out the other ladies participating...
