I've not yet done a completely stand-alone 3D figure. Im making Brutus Buckeye, what would I use for the supports inside, to then add krispy treat around? Do they make pvc that little? I'd like the figure to be about a foot tall or better. So I'd need pvc small enough to get the right scale. Any options let me know!

Have you thought about using wooden dowels for your support? You can get pretty small ones at any home depot type store. You could also screw it into a wooden cake base for more support. Just a thought..... Good luck.
