Today was 112°F here in Las Vegas, and I felt like I was melting even INDOORS with air conditioning. I saw a wonderful gradient on Michelle of All Lacquered Up's blog. She used one off the butterLONDON jellies layered 4 times to create a pretty effect. I loved the effect of the jelly layering so much, I decided to do my own- I used a polish that took about 5 layers to be opaque, and I think it worked perfectly for this effect.
I used Nicole by OPI Respect the World Matte as a base, with Confetti My Favorite Martian sponged over it in three layers. Topped it all off with 2 coats of Seche Vite top coat.
