Work on the Avatar has been somewhat long and labor intensive but it's coming along. Here's what the sword is looking like. I started by cutting off the tip of the sword and then sketched out the shape I wanted to use to extend the sword on a thick piece of plasticard. I then cut out my shape and added a couple layers of super thin plasticard cut concentrically smaller to get the proper thickness and rough shape.
I used my dremel to sand the piece into shape. Then I pinned and glued it onto the lower sword half and puttied in the gaps.
Progress so far
