dolls and questions~

hello~
i followed a link from the DoA subforums here and i look forward to spending more time here.
currently my status is as an observer though i hope to change that soon. i am currently in the process of carving out my styrofoam core for my doll. she will be a small doll, about 30 cm as i do not want to start out big. she is meant to have a cute but curvy body so i can dress her up.
there are many questions i have unanswered about doll making but i do not wish to delay making my doll any longer. so perhaps they will perhaps be answered by trial and error.
one of the questions i have unanswered is how to attach the headcap to the head.
another question is how to create the joint in the mid-section of the body. is the answer to sculpt the body first and then add a mid-joint after removing the core like in the legs?
another concern would be the eyes and hair. there is no doll shop here so i cannot buy the eyes and hair off the shelf. i also don't know whether my doll size is 'standard' enough to buy a wig off one of the companies selling dolls. >_<... perhaps i will buy a wig cap and follow one of the tutorials for making wigs. then i can say the doll is entirely mine~ but the thought is intimidating. so i will not think about it any further.

btw~ to the first person who tells me the correct meaning of my name, i will give them a cookie~
