Another Bevy of Links

Did a search for "action figure custom tutorial" and found this nice tutorial on making a custom DCU Question.

Then there's this page on 1/6 figures, which has a few tips and links.

And this page on custom anime figures, with lots of nice links to video tutorials on painting and sculpting.

This page on Instructables has some good tips on making a custom action figure. He suggests nail polish remover to get the excess paper and whatnot off the bubble.

This thread has some good links, including this one which has lots of promise and lots of tutorials, including tool and material reviews. Definitely worth more investigation. He also has great things to say about the Fwoosh forums.
