I know, the quality sucks and the music is...um...amazing. This is my first video tutorial though, so please be nice! I was also working under lamp light and was trying to keep my finger from blocking the camera, so the polish kind of got gloopy on me. I think you'll get the idea though. Video tutorials are hard! I don't think I will do more in the future unless it's hard to show through pictures like needle marbling. Either way, I hope it helps!
Here are also some more pics of needle marbling. Which one's your favorite? (View previous look here.)
