Have You Ever Made Your Own Makeup?

I've created my own lip balm, sunblock, and solid perfume over the years, but I have yet to venture into the world of DIY makeup. Recently, however, a friend who paints using her own pigments decided to turn her colors into eye shadows and lipstick, and the results were fabulous on her (almost anything would be, though). I started to think about all the pigments and mediums out there, and I wondered how many of you have experimented with creating your own cosmetics. So how about it? Have you ever converted something into makeup?
