I think I saw this technique somewhere, but can't remember for sure. I did have a few goof's, which I will tell you about those after the pictures and let you know how NOT to mess up like I did.
I'll start by telling you what I did do. I used Wet N Wild I Red A Good Book & Wet N Wild Black Creme for this mani. I put red on my index and middle fingers(one at a time) and used a somewhat thick coat. While that was still wet, I put a few small drops of black on top. Then, using a dotting tool that has an end similar to a needle or toothpick, I swirled the two colors together. I placed black on my ring and pinky fingers then did the same with the red. I did not use any top coat.
Now, I'll tell you how I goofed this up. I started out with my index finger and accidentally placed too much black so I had to add a little bit of red, which made it darker. I also went a little too deep with the tool and kinda left a few scrape looking marks in the polish down to the nail. I was able to fix a few spots, but missed others. Those aren't bubbles, but where I went too deep. I possibly could've corrected and filled in those little gaps with top coat, but I had to hurry up and remove this so I could run some errands.
I will definitely be trying this again. What do you think?
