For this this nail art, I used my straight tile nail stencils which you can buy from my Storenvy.
I decided to just make the tutorial into a GIF so this post would not be too picture heavy.
1. Start with a white base.
2. Place the straight tile nail stencil in any direction that you want.
3. Paint one side with red nail polish, and the other side with blue nail polish.
4. Slowly remove the nail stencil, apply your favorite top coat, and you are done! :)
Here are more photos of the nail art. For my other fingers, I stamped it with an image from MoYou London Fairytale 4.
Here are some close-up shots of the nail art.
