Oooh... nice job! Keep it up.

Say, Propoxy, is that perhaps some kind of epoxy clay?
I've read that Sculpey gets brittle and breaks easy. How thin is not good to go beyond if I don't want it to break easily?

Thanks for a great tutorial! You should ask the people at CA to host the images when you're done so that the tutorial will stay on the forum!

EDIT - Sorry, I should read more closely in the future. I saw the post where you wrote that you used an epoxy putty named Propoxy.
