Help!

I went away from the computer after my last post enthusiastically, and got out pen and paper and started drawing up a plan of a rag-doll. I hadn't even finished the first drawing before i knew it wasn't working.

Please, I need help!! Does anyone know how to make a rag-doll?? I can't find any good instructions online. When I say 'rag' doll i dont mean something scrappy, just a hand-sewn doll with detatchable clothes (possibly - or I could just make a new doll for each outfit ...)

Anyway, even a suggestion would be nice! My main dilemmas are how to make it so the arms and legs could bend, how to make feet that aren't just blobs (cause i'd wanna make shoes too) and yeah...

Also, do you think I should make it shape-y with a proper waist and everything, or just make it quite straight??

Please give ideas!!!
