i made one version, but didn't add any 'smelly' stuff to it and it smelled like rice that had been microwaved. i used it though, and it helped a lot! i decided to make another that smelled good! so that i wasn't disgusted while in labor - i added a lavender dryer pouch from trader joes with the rice. it's practical and cute :). it even has an inner bag with the rice and stuff that can be thrown away when it starts to not smell or smell like old rice!
