Here is my first franken: Rusty. Rusty is made from a horrible clear Max Factor polish and a brown loose eyeshadow. I don't use loose eyeshadow, so I figured it would be cool to make it into a nail polish. The eyeshadow was really pretty. Warm brown with blue sparkles. The frankenpolish looks like rust. I didn't put any mixing ballz in there, since I'm too lazy to go buy some.
