Update

I finally heard back from Burns Family Studios, and we have some more ideas. The ideas are: We might order a big shipment of wedding bands, entwine them, spray paint them silver, and.... we would have chain mail! For actual armor we might use recycled youth hockey pads. For bows, painted PVC pipe! For arrows, wooden dowels with feathers! For the extras' swords we might stuff plastic swords with spray-foam insulation! And lastly.... we might use cardboard cereal boxes for spears and axes.
