I'm now making armatures available for those who would like to sculpt their dolls in the exact size I have made mine. Watch the video below to see the armature. These are made by hand, so they will ship a day or two after you order.
This armature is the size I used in Sculpting a Young Fairy. The arms and legs are a bit long so you can trim them as you desire. If you are bending the limbs, you'll need more wire than you would with a straight limb. This armature accommodates both styles.
The armature in the video below is for the male, but it gives you an idea of what these are like to handle.
