Not only did I use foam for the arms on this figure, but I made the sword from it too. I have been re-thinking which elements should be foam and which should be wood (or some other material). On my upcoming French Napoleonic Carabiniers (1807) you will see some new uses of foam. I am putting the finishing touches on the horse's paint jobs, so it should not be long. But, I will be making their swords from foam too. I decided to try a few foam weapons because of all the "casualties" I have had with my figures so far, it is the wooden swords that have fallen off the most, My theory is that because the wood does not flex, when the figure is accidentally bumped or dropped, all it can do is absorb the impact (i.e. glue holds, but is weakened) or break. The foam will flex, so it should survive. We will see, and I will report on it here.
I have already started building my Anglo-Danish army for Saga. I have the basic figure, helmet, feet, and base for eight Hearthguard and eight Warriors. I am still working on the 12 Levy, but they are almost complete (making them, that is; painting still a ways off). As for an opposing army, that is even further off.
