I used to make reborn dolls until I couldn't afford to anymore (it's an expensive business!)
Reborn dolls are basically expensive dolls made of soft realistic touch vinyl by a doll company. The reborner buys these dolls, takes them apart, removes their nasty wig, stuffing and paint, and "reborns" (stupid term) them into a better more realistic doll by opening up their nostrils, giving them individually rooted hair, glass eyes, weighting them realistically so the head is heavy and floppy like a young baby, painting their skin inside and out to give them realistic alive looking fleshtones, and finally dressing them to look like a real baby and selling them for anything from £50-£400. There are loads on ebay.
And can I just say that I'm not a weirdo, I have an art degree and I enjoyed making the dolls as realistic as possible, it was a lot of fun and took a lot of technical skill, I don't have some kind of weird unresolved baby issues!! lol
However, I can't vouch for the people who buy them (I wouldn't buy one, I'm not sure what they get out of owning them)
