How is it that you haven't used the "Air Dry" sculpy?? I'm not a big fan of the oven dry stuff, but my kids love it.
The over dry stuff is okay for building a base, but I would think you'd have been using the air dry if you were using styrene instead of the oven dry which works well with a traditional wire frame.
I've seen more than a few examples of entire figures being sculpted from the air dry stuff with amazing results. I still haven't gotten my hands on any though.
Like usual, Joe, you're presentation is amazing. Good to see someone with your talent level writing up the articles here. You're first class, mate.
