Momiji is having a contest, and it's right up your alley! (Well, probably.)
From their site:
"Momiji are message dolls, each doll has a space in its base for a secret message. Our Couture Contest is a playful new direction; we’re looking for one-off, fabric dolls. You can create your doll using a combination of any textile methods you like; weaving, printing, knitting, embroidery....the list goes on."
Check out all the details at http://lovemomiji.com/couture/.
But hurry, because the deadline is October 30th!
