These nails were directly inspired by Lachesis and Co. I used a slightly different teal polish because I don't have Turned Up Turquoise in my stash. I used Sinful Colors Savage.
Here is a photo progression of how I did these.
Started with a base of Sally Hansen Complete Salon Manicure Lavender Cloud.
Sideways sponge gradient with SH LC and Sinful Colors Savage.
Stamp with BM12 and Konad Special Black polish.
Finish with Seche Vite topcoat.
