I started with one of my new fave holos - Butter London Fishwife. What a weird name for such a beautiful polish!
This look from her site, referencing a Diane Von Furstenberg dress, caught my attention, so I thought to do my version. After BL Fishwife dried, I cut a piece of tape with craft scissors so that it was narrow, but textured on both sides. I placed that piece of tape in the center of my nail, and painted BL Scallywag on the exposed sides of my nails.
