Hi Butterfli 19 - Sounds like a wonderful idea! The pattern that I use for dolls (I think they're 19") is the Mommy Make Me pattern from Fairfield - the people who make the poli-fill stuffing. Please go to their website - you'll find some wonderful ideas. including (I think) the little doll that you want to make.
