I love this nail art, but it definitely took some trial and error. I used two polishes: ILNP Mega (S), a linear silver holo, and Born Pretty Mirror Nail Polish. I couldn’t get the holo to show up much even with outside lighting, but in person it’s definitely holographic.
I first used a peel-off base coat which was a mistake, but it totally slipped my mind until it was time to peel off the vinyls. Once I switched base coats, the mirror polish became the problem since it requires a special base coat. Once the base coat dried it kept sticking to the edges of the vinyls so by the time I applied the mirror polish itself it would pull up when removing the vinyls. I solved this by sponging on the base coat instead of just using the brush. This is a subtle design, but it looks really cool especially up close.
