I saw a tutorial on how to do this from Nailside! She does awesome nail art! If you havent looked at her blog yet go check it out! When I saw this tutorial I immediately wanted to try it! So here's the result!
I put matte topcoat because the colors showed up better :)
The colors dont show up like this in real life :( but oh well. In the pictures the lines are pink and the base color is orange. But you can barely see the pink lines in the picture D:
