Figure 12-98 shows a subdivided version of the hand at the current
step (left). Select the marked polygons, extrude forward, and scale
down.
Before continue with the extrusion we need to make the thumb a
little rounder and continue extruding until we get the whole thumb
done. In looking at the thumb from the side, we can clearly see that
we must rearrange the vertices a little bit.
Notice the difference in the thumb after some tweaking (below,
left). The images at the center and right of Figure 12-100 show the
wire mesh and subdivided versions of the hand.
