This look took awhile to do. I started with a red, yellow and blue gradient using Essie Really Red, China Glaze Sunshine Pop and OPI Fly. After the gradient was complete I did a water marble using China Glaze Liquid Leather and Julep Melissa. Since Melissa is a shimmery see through it let the gradient through!
I'm going to try this again because I'm really only happy with how the thumb came out, but it's a great first try.
