By the Pricking of My Thumbs is an homage to bloodstone, and a very specific still from the Abominable Bride. I started with a teal/green toned grey base with red to violet shimmer and a ton of linear holo. I'm so in love with this polish. It combines four of my favorite things: Sherlock, Holo, Grey, and Shiftiness. So stunning.
