With new faces must come new bodies, right?
The crucial parts of a ball-jointed doll are the joints. For mine, I've been using wood beads. To accommodate the movement of the elastic through the joint, I've widened the bead holes into slits using a small bow saw.
For the bodies, I've been using Super Sculpey. On these arms and legs (as well as Morgan's torso), however, some quickly-made terra cotta sculpey will do. At least, for the moment.
