Painting resin eyes

Continuing working on my second head build, just posted this blog entry about painting resin eyes: http://www.sanssoucistudios.com/blog/painting-resin-eyes

My first head I used both acrylics and watercolor pencils, this time I used straight acrylics- felt like I had more control.

I'm curious- how many people here paint their own eyes, or buy them pre painted? If you paint them yourself, are there tutorials you find especially helpful? Links? I know there's also those photo printouts that get glued to eyes that look pretty nifty, what do you use?

Thanks in advance!
