Rice works. Cute chicks!

Very cute, bird grit in the pet section of almost any store works great and is cheap.

SEEEWWW cute Connie!!

Crushed walnuts , can be bought at pet supply stores.

those are so cute

Congratulations!! I've made a couple of those and they are very time consuming or at least they were for me but they are so darn cute. The best thing I've heard of for stuffing pin cushions is ground walnut hulls. It is in kitty litter and can be purchased at a pet store. Our LQS sells it in small bags.
