I've decided to go life sized with the silhouettes at this stage.  I achieved this by drawing the figures on asotate and placing them on an overhead projector facing the wall which I had covered previously with black paper.  This is the projector I used.

I then drew the outline of the shadow onto the black paper using white chalk.  Once I had my outline, I was able to cut the figure out using a scalpel.  At the beginning I tried using a scissors but it didn't cut as smoothly as the scalpel.  Here are a few life sized pieces that I've done so far in the project.
