Basic tools and materials of doll-making. (game?)

Dentist tools. I've recently dicovered that medical scalpels are compatible with x-acto knife bases.
Pros: They're cheaper than hobby-supplies, come in many shapes and quite sturdy.
Cons: Having to explain yourself everytime you go to the dentist-supplies shops.

 

Thick Crafting/Floral Foam-

It's a good way of carving out the basic shape of the doll before adding clay and sculpting details.

Pros: It makes the prototype doll light weight and quicker to make.
Cons: If you press too hard on it (before or after covering w/clay) could cause the foam to compress.

Apoxie Sculpt
A lot of doll makers and modders use it and it acts like sculpey, but dries like air dry clay.
Sadly, its pretty expensive, and you don't get much.
