No doll can stand up by itself when it hasn't been made well-balanced in its construction.
Step by step process of making a ball jointed doll
(1) Drawing up a plan
For a start, draw up a plan in same size, the front and the side, taking account of the balance of each part, and the size of joints (figure on the right). This doll will be 2 feet tall.
Mixed sawdust turns into hard and light after it is dried up.
The styrofoam core is to be raked out later, then every parts will be hollow.
Mix the same quantity of sawdust and CMC (chemical paste mixed with water. If CMC is not available, starchy paste can be used) and knead with hand until it becomes clayey.
Don't make too much, since it will get dry or rotten after a few days.
Put all over the surface except the joints parts in about 2mm thick uniformly, then dry them up.
If somewhere fissures, then fill it up and dry again perfectly.
Put the mark of up and down, right and left at the surface of joints.
Knead the same quantities of sawdust and stoneclay.
For the first put the mixed base uniformly, and put the mark for modeling.
Don't use fiber-tipped pens, because ink would influence the surface later.
Colored pencils or conté crayons are suitable.
Figures show the state of being fleshed out roughly.
After the shape of the head has decided, make the neck by the same way of the other parts. (Use the styrofoam inside for the core.)
The base of hands
Draw the picture of a hand, and make palms with sawdust. Cut stainless steel into ten pieces for fingers.
Make holes for fingers, four on the top of the palm and one inside the palm with a pinvise (tiny drill).
