Thanks Doomsdayrenderer.

I already knew about your second 2 links - in fact, they're how I figured how to unwrap and texture my head.

The first link will be VERY useful, thanks.  I've bookmarked it.  I'll need to read it a bit more carefully, because I would have sworn I HAD done what it says for multiple UV layouts... but when I export one, they all come out superimposed on top of each other in the one image.  I need to go through it more carefully.

I think this time I'm going to stick with Blender and not quit after a week or two...

Thanks again!
