I got the 20 inch pattern from Little Joys and you can get the star pattern from Magic Cabin but you really don't need the pattern if you know how to construct the head.
I ordered alot of the cotton velour fabric from Little Joys (she gives a bulk discount and i make alot of dolls) It is not pure cotton, i haven't found that anywhere but it is mostly cotton and it feels great.
I think there is a thread somewhere from LaLa that gives instructions on making the head.
If you need the # for Little joys let me know. I can get it later.
