Thank you Rich H for the explanation and the photographs. I think your and Michi's plasticard models look great! The method you described will work fine for me when I get to do some WH40K Rogue Trader conversions of the scifi plastic model kits. For the fantasy model pieces' flags and banners made of thin plasticard, I guess I could try the same wraparound method to make the parts of the banner that bend over the horizontal pole to secure it. So far that has been the hardest thing to do by heating, as those small plastic flaps tend to shrink or bend away in a very uncontrollably manner when heated.
