Putting the skin on the bones
This stick figure will be the bones of the figure. Blender has a very cool modifier that will thicken any stick mesh into a full bodied mesh. It is called, appropriately enough, Skin.
Add the Skin modifier to the mesh
It might not be immediately apparent, but now every stick has a 3-dimensional shape wrapped around it. To make the effect more apparent, use the Skin Resize (Ctrl + A) operator. This will be a temporary step to see the effect first:
Select all points (A).
Move the mouse pointer to a point closer to the center of the skeleton.
Press Ctrl + A to begin the Skin Resize operation.
Move the mouse pointer away from the skeleton until the mesh thickens up.
Left-click to complete the operation.
The skin resize operator can alter each point independently so the shape does not have to be uniform.
Undo (Ctrl + Z) the previous operation back to a thin sticks all around.
Select (right-click) the vertex where the legs meet and Skin Resize (Ctrl + A) to make a nice big...
