I make rice bags ever year for my family. I buy mens tube socks cut off the top and fill the sock with rice. I have even keep the top of the sock that i just cut off and make little rice bags out of them. They are only about 4 " long but work great if you have a ninus headache and to not want a big rice setting on your face. Than i make pillow case's out of feft over flannel and slip on the bags, than you can wash the covers any time you need them.. I make the covers out of pink or pretty covers for my girls and for the boys i use red or blue dark plaid. It works great. To fill the bags i use one of my tupperware containers and put the pot on the sock around the top of the container " it is about 12 " high. I think it is for juice, put a large rbber band around the sock and fill with rice.
