help with moulding

I just bought some liquid rubber to make a mould from a dolls face that I have. I want to make many copies of this face as I want to make my own Mrs Santa dolls. I have read all the directions on making the mould. My question is once the mould is made how do I make the copies and with what materials can I use for the faces. The current doll is a hard plastic face mask. She has a chin and ears but the eyes and lashes are painted on. Is there a fleah tone type plastic that I can use or should I try using poly clay? Any help is appreciated. smidget
