Welcome to Gaia! ::

Sorry for the images and their awkward light, I don't have a scanner, only a camera. ._.

Many places. They are called ball-jointed dolls, the normal abbreviation being BJDs (or ABJDs.)

Some companies are...
http://www.eluts.com
http://www.doll-zone.com
http://www.iplehouse.net
http://www.dreamofdoll.com

And many, many others. My doll is from Doll-Zone, the model is Ian. I am aiming for another. :3 I practice me sewing of costumes on him (yes, he is male,) and some jewelry-making.

There is actually one place that sells centaur bjds, but I am unsure of which it is or even if it was actually a custom job shop by an artist.

Photostories, there are quite a few people out there that make them. I plan to be one as soon as I get another doll. XD

A good source of information about these dolls is http://www.denofangels.com/forums/ but I don't like going on there anymore.

I sew and attempt my own costume designs on him. :3 I also make jewelry for him.

I'd kill to go to a convention of FaerieCon, but I am putting that on hold.

As soon as I finish his current outfit, I'll post up a picture of it.
