My son is still very much against the idea of the satyr or Cyclops legs. The first time he seemed against it, I thought perhaps he was just tired. I had my husband show him "Narnia: The Lion, The Witch, and The Wardrobe" so he could see Mr. Tumnus (the satyr). He seemed to like the character, but when I showed him the fake fur and put it over his leg, he made it clear he didn't want it.
So, what to do???
After some thought and tossing around ideas, I think I've settled on continuing the Elfling costume. A quick tunic, a belt, a cowl, and a fake fur cape. Should be cooler but with more coverage for the skin. I'm not sure how many of these pieces will be finished in time, but it will be interesting to find out.
The plus side of this change is that he can choose to be an elfling or he can choose to be a Viking (by simply leaving off the cowl and adding his Viking helmet)!
At least I have some direction with this now.
