Ok, I think I'm in like with this technique. Finally, a use for those wonderful pictures in old National Geographic magazines (you know the ones you hang onto because they are too good to throw out, but absolutely nobody wants them and you can't think of a use either??). Well. I found a use.
These are now cut up into atc size and now I will experiment with maybe some metallic paints - perhaps drybrushed on top. The trouble now is that I don't want to ruin them - they're nice as they are!
