Here are a few pictures I took while modding this tiny dolly. It just gives you a general idea of how to go about it and doesn't go into detail on how to add hair. However, it is not hard to figure it out. :) I hope it helps!
Then add glue and apply mohair. I used tacky glue and it worked very good to hold the mohair in place. You could also add yarn instead of mohair for a "Raggedy Ann" style doll. :)
