I used four different colors, a brush, and some acetone. There are instructions and a link to a how-to video on Chalkboard's post! Go check it out.
The base is Wet n Wild megalast Hush Hush/Ultra-Secret. The Purple is Zoya Demi (not only do I LOVE the color, it also has my name)! The blue is N.Y.C. 115A and the yellow is 114A. I haven't used these two since high school. Using them now made me remember why. They were hard to work with. =/
They didn't turn out amazing, but they are full of color and fun to look at!
My top coat is Sally Hansen's Insta-Dri. For some reason I am LOVING this top coat. Not only does it give a great shine, my manis seem to last for days with it on.
