These photos show  making a cardboard outline to shape a tsa-tsa figure. I did fill in to this figure several months ago and am now ready to sand back to the shape I want.  The shape is sufficient to cut it back to the target shape but I will still need to do filling out to make it thick enough.  There are also cracks to fill, it looks like this piece was broken into about 4 pieces and someone glued it back together.  The photos show the final, cardboard outline. The black areas show where I need to shave back.
