yea.. cotton is free..first u bring the bear skin to the cotton machine.. the staff will then fill the cotton inside the bear skin for you....by the time it's almost done.. she will ask u if this looks ok.. then u told her to put more cotton on the bear's tummy.. she will stuff more cotton in without extra charges. you have to ask her to stuff more.. just tell her the kids want a big FAT tummy bear.. she will smile and do it for u~ That's was I did to make a FAT bear.. hahahaha
